+[Excerpt from an email describing how to build Python on AIX.]
+
+
+Subject: Re: Python 1.0.0 BETA 5 -- also for Macintosh!
+From: se@MI.Uni-Koeln.DE (Stefan Esser)
+To: Guido.van.Rossum@cwi.nl
+Date: Fri, 7 Jan 1994 17:40:43 +0100
+
+[...]
+
+The following are [...] Instructions
+to get a clean compile using gcc and xlc
+under AIX 3.2.4.
+
+Since I wanted to make sure that Python compiles
+using both compilers and several sets of options
+(ANSI and traditional C, optimize on/off) I didn't
+try to include bash readline or other optional 
+modules.
+
+'make test' succeeded using Python compiled with 
+the AIX C-compiler invoked as 'cc' and with options 
+'-o -qMEMMAX=4000' and compiled with 'gcc' and 
+options '-O -Wall'.
+
+There were some problems trying to compile python
+using 'gcc -ansi' (because of _AIX no longer being
+defined), but I didn't have time to look into this.
+
+
+
+Regards,
+
+Stefan Esser
+
+
+
+
+REQUIRED:
+---------
+
+1) AIX compilers don't like the LANG env
+   varaiable set to european locales.
+   This makes the compiler generate floating
+   point constants using "," as the decimal 
+   seperator, which the assembler doesnt't 
+   understand (or was it the other way around,
+   with the assembler expecting "," in float
+   numbers ???).
+   Anyway: "LANG=C; export LANG" solves the 
+   problem, as does "LANG=C $(MAKE) ..." in 
+   the master Makefile.
+
+OPTIONAL:
+---------
+
+2) The xlc compiler considers "Python/ceval.c"
+   too complex to optimize, except when invoked
+   with "-qMEMMAX=4000".

+What is Python?
+---------------
+
+Python is an interpreted, interactive, object-oriented programming
+language.  It incorporates modules, exceptions, dynamic typing, very
+high level dynamic data types, and classes.  Python combines
+remarkable power with very clear syntax.  It has interfaces to many
+system calls and libraries, as well as to various window systems, and
+is extensible in C or C++.  It is also usable as an extension language
+for applications that need a programmable interface.  Finally, Python
+is portable: it runs on many brands of UNIX, on the Mac, and on
+MS-DOS.
+
+As a short example of what Python looks like, here's a script to
+print prime numbers (not blazingly fast, but readable!).  When this
+file is made executable, it is callable directly from the UNIX shell
+(if your system supports #! in scripts and the python interpreter is
+installed at the indicated place).
+
+#!/usr/local/bin/python
+
+# Print prime numbers in a given range
+
+def main():
+	import sys
+	min, max = 2, 0x7fffffff
+	if sys.argv[1:]:
+		min = int(eval(sys.argv[1]))
+		if sys.argv[2:]:
+			max = int(eval(sys.argv[2]))
+	primes(min, max)
+
+def primes(min, max):
+	if 2 >= min: print 2
+	primes = [2]
+	i = 3
+	while i <= max:
+		for p in primes:
+			if i%p == 0 or p*p > i: break
+		if i%p <> 0:
+			primes.append(i)
+			if i >= min: print i
+		i = i+2
+
+main()

+Newsgroups: comp.lang.perl,comp.lang.tcl

+Subject: Python (was Re: Has anyone done a tk addition to perl?)
+Organization: XVT Software Inc.
+Date: Thu, 14 Oct 1993 17:10:37 GMT
+X-Disclaimer: The views expressed in this message are those of an
+	individual at XVT Software Inc., and do not necessarily

+
+
+I've gotten a number of requests for information about Python,
+since my post here earlier this week.  Since this appears to be 
+of general interest, and since there's no python news group yet, 
+I'm posting a description here.  I'm not the best authority on 
+the language, but here's my take on it.  
+
+[TCL/Perl zealots: this is informational only; I'm not trying to
+'convert' anybody, and don't have time for a language war :-)
+There is a paper comparing TCL/Perl/Python/Emacs-Lisp, which is
+referenced in the comp.lang.misc faq, I beleive.]
+
+
+What is Python?...
+
+Python is a relatively new very-high-level language developed 
+in Amsterdam.  Python is a simple, procedural language, with 
+features taken from ABC, Icon, Modula-3, and C/C++.
+
+It's central goal is to provide the best of both worlds: 
+the dynamic nature of scripting languages like Perl/TCL/REXX, 
+but also support for general programming found in the more 
+traditional languages like Icon, C, Modula,...
+
+As such, it can function as a scripting/extension language,
+as a rapid prototyping language, and as a serious software
+development language.  Python is suitable for fast development
+of large programs, but also does well at throw-away shell coding.
+
+Python resembles other scripting languages a number of ways:
+    - dynamic, interpretive, interactive nature
+    - no explicit compile or link steps needed
+    - no type declarations (it's dynamically typed)
+    - high-level operators ('in', concatenation, etc)
+    - automatic memory allocation/deallocation (no 'pointers')
+    - high level objects: lists, tuples, strings, associative arrays
+    - programs can construct and execute program code using strings
+    - very fast edit/compile/run cycle; no static linking
+    - well-defined interface to and from C functions and data
+    - well-defined ways to add C modules to the system and language
+
+Python's features that make it useful for serious programming:
+    - it's object-oriented;  it has a simplified subset of 
+      C++'s 'class' facility, made more useful by python's
+      dynamic typing;  the language is object-oriented from
+      the ground up (rather than being an add-on, as in C++)
+
+    - it supports modules (imported packages, as in Modula-3);
+      modules replace C's 'include' files and linking, and allow
+      for multiple-module systems, code sharing, etc.;
+
+    - it has a good exception handling system (a 'try' statement,
+      and a 'raise' statement, with user-defined exceptions);
+
+    - it's orthogonal;  everything is a first-class object in the
+      language (functions, modules, classes, class instance methods...)
+      and can be assigned/passed and used generically;
+
+    - it's fairly run-time secure;  it does many run-time checks
+      like index-out-of-bounds, etc., that C usually doesn't;
+
+    - it has general data structuring support;  Python lists are
+      heterogeneous, variable length, nestable, support slicing, 
+      concatenation, etc., and come into existance and are reclaimed 
+      automatically;  strings and dictionaries are similarly general;
+
+    - it's got a symbolic debugger and profiler (written in python, 
+      of course..), and an interactive command-line interface;
+      as in Lisp, you can enter code and test functions in isolation,
+      from the interactive command line (even linked C functions);
+
+    - it has a large library of built-in modules;  it has support
+      for sockets, regular expressions, posix bindings, etc.
+
+    - it supports dynamic loading of C modules on many platforms;
+
+    - it has a _readable_ syntax;  python code looks like normal
+      programming languages;  tcl and perl can be very unreadable
+      (IMHO; what was that joke about Perl looking the same after
+      rot13..);  python's syntax is simple, and statement based;
+
+
+Of course, Python isn't perfect, but it's a good compromise betweem
+scripting languages and traditional ones, and so is widely applicable. 
+'Perfect' languages aren't always useful for real-world tasks (Prolog, 
+for example), and languages at either extreme are not useful in the other 
+domain (C is poor for shell coding and prototyping, and awk is useless 
+for large systems design; Python does both well).  
+
+For example, I've used Python successfully for a 4K line expert system 
+shell project; it would have been at least twice as large in C, and would 
+have been very difficult in TCL or Perl.
+
+Python uses an indentation-based syntax which may seem unusual at first
+to C coders, but after using it I have found it to be _very_ handy, since 
+there's less to type.  [I now forget to type '}' in my C code, and am 
+busy calculating how much time I wasted typing all those '}', 'END', etc., 
+just to pander to 'brain-dead' C/Pascal compilers :-)].
+
+Python's currently at release 0.9.9.  It seems suprisingly stable.
+The first 'official' 1.0 release is due out by the end of this year.
+Python runs on most popular machines/systems (mac, dos, unix, etc.)
+It's public domain and distributable, and can be had via ftp.  The 
+distribution includes examples, tutorials, and documentation.   The 
+latest ftp address I have (I got it on a cd-rom):
+    pub/python/*  at  ftp.cwi.nl
+    pub/?         at  wuarchive.wustl.edu   (in america)
+
+There's a python mailing list maintained by the language's creator.  
+Mail 'python-list-request@cwi.nl' to get on it.

+
+
+1. General information and availability
+=======================================
+
+1.1. Q. What is Python?
+
+A. Python is an interpreted, interactive, object-oriented programming
+language.  It incorporates modules, exceptions, dynamic typing, very
+high level dynamic data types, and classes.  Python combines
+remarkable power with very clear syntax.  It has interfaces to many
+system calls and libraries, as well as to various window systems, and
+is extensible in C or C++.  It is also usable as an extension language
+for applications that need a programmable interface.  Finally, Python
+is portable: it runs on many brands of UNIX, on the Mac, and on
+MS-DOS.
+
+To find out more, the best thing to do is to start reading the
+tutorial from the documentation set (see a few questions further
+down).
+
+1.2. Q. Why is it called Python?
+
+A. Apart from being a computer wizard, I'm also a fan of "Monty
+Python's Flying Circus" (a BBC comedy series from the seventies, in
+case you didn't know).  It occurred to me one day that I needed a name
+that was short, unique, and slightly mysterious.  And I happened to be
+reading some scripts from the series at the time...  So then I decided
+to call my language Python.  But Python is not a joke.  And don't you
+associate it with dangerous reptiles either!
+
+1.3. Q. How do I obtain a copy of the Python source?
+
+A. The latest Python source distribution is always available by
+anonymous ftp from ftp.cwi.nl [192.16.184.180] in the directory
+/pub/python, with filename python<version>.tar.Z.  It is a compressed
+tar file containing the complete C source, LaTeX documentation, Python
+library modules, example programs, and several useful pieces of freely
+distributable software.  This will compile and run out of the box on
+most UNIX platforms.  Currently <version> is 0.9.9.  (See section 7
+for non-UNIX information.)
+
+1.4. Q. How do I get documentation on Python?
+
+A. The latest Python documentation set is always available by
+anonymous ftp from ftp.cwi.nl [192.16.184.180] in the directory
+/pub/python, with filename pythondoc-ps<version>.tar.Z.  It is a
+compressed tar file containing PostScript files of the reference
+manual, the library manual, and the tutorial.  Currently <version> is
+0.9.9.  (Note that the library manual is the most important one of the
+set, as much of Python's power stems from the standard or built-in
+types, functions and modules, all of which are described here.)
+PostScript for a high-level description of Python is in the file
+nluug-paper.ps.
+
+The following sites keep mirrors of the Python distribution:
+
+Site			IP address 	Directory
+
+gatekeeper.dec.com	16.1.0.2	/pub/plan/python/cwi
+ftp.uu.net		192.48.96.9	/languages/python
+ftp.wustl.edu		128.252.135.4	/graphics/graphics/sgi-stuff/python
+ftp.funet.fi		128.214.6.100	/pub/languages/python (old?)
+ftp.fu-berlin.de	130.133.4.50	/pub/unix/languages/python (python* only)
+
+Or try archie on e.g. python0.9.9.tar.Z to locate the nearest copy of
+that version...
+
+1.5. Q. Is there a newsgroup or mailing list devoted to Python?
+
+A. There is no Python newsgroup yet; if you want to post to the net
+about Python, use comp.lang.misc.  There is a mailing list devoted to
+Python; send e-mail to python-list-request@cwi.nl to (un)subscribe.
+There are plans to start the discussion about creation of
+comp.lang.python as soon as version 1.0.0 has been released.
+
+1.6. Q. Is there a book on Python, or will there be one out soon?
+
+A. Unfortunately, not yet.  I would like to write one but my
+obligations at CWI include too much other work to make much progress
+on it.  Several parties have expressed interest in sponsoring or
+helping the production of a book or reference manual, but so far there
+are no firm plans.  If you volunteer help, by all means drop me a
+note!
+
+1.7. Q. Are there any published articles about Python that I can quote?
+
+A. So far the only refereed and published article that describes
+Python in some detail is:
+
+    Guido van Rossum and Jelke de Boer, "Interactively Testing Remote
+    Servers Using the Python Programming Language", CWI Quarterly, Volume
+    4, Issue 4 (December 1991), Amsterdam, pp 283-303.
+
+LaTeX source for this paper is available as part of the Python source
+distribution.
+
+A more recent high-level description of Python is:
+
+    Guido van Rossum, "An Introduction to Python for UNIX/C
+    Programmers", in the proceedings of the NLUUG najaarsconferentie
+    1993 (dutch UNIX users group meeting november 1993).
+    
+PostScript for this paper and for the slides used for the accompanying
+presentation can be found in the ftp directory mentioned a few
+questions earlier, with filenames nluug-paper.ps and nluug-slides.ps,
+respectively.
+
+
+2. Python in the real world
+===========================
+
+2.1. Q. How many people are using Python?
+
+A. I don't know, but at the last count there were at least 130
+addresses on the Python mailing list (several of which are local
+redistribution lists).  I suspect that many users don't bother
+to subscribe to the list.
+
+2.2. Q. Have any significant projects been done in Python?
+
+A. Here at CWI (the home of Python), we have written a 20,000 line
+authoring environment for transportable hypermedia presentations, a
+multimedia teleconferencing tool, as well as many smaller programs.
+
+The University of Virginia uses Python to control a virtual reality
+engine.  Contact: Matt Conway <conway@virginia.edu>.
+
+See also the next question.
+
+2.3. Q. Are there any commercial projects going on using Python?
+
+A. Several companies have revealed to me that they are planning or
+considering to use Python in a future product.  The furthest is
+Sunrise Software, who already have a product out using Python -- they
+use Python for a GUI management application and an SNMP network
+manangement application.  Contact: <info@sunrise.com>.
+
+Individuals at many other companies are using Python for
+internal development (witness their contributions to the Python
+mailing list).
+
+Python has also been elected as an extension language by MADE, a
+consortium supported by the European Committee's ESPRIT program and
+consisting of Bull, CWI and some other European companies.  Contact:
+Ivan Herman <ivan@cwi.nl>.
+
+2.4. Q. What new developments are expected for Python in the future?
+
+A. I am almost ready to release version 1.0.0 -- it should be out by
+the end of January 1994.  It will have some new functionality and
+bugfixes and be portable to more platforms.  The directory tree
+structure and build procedure will be radically different -- almost
+all configuration is now done automatically, using GNU autoconf.
+User-visible changes include: double-quoted strings, functional
+programming operations (lambda, map, filter, reduce -- all evaluated
+eagerly), exec becomes a statement, str() is customizable through
+__str__ (used by print).  The originally planned grand renaming scheme
+will not be implemented because of lack of time.  A beta version can
+be ftp'ed from the usual sites, file python1.0.0beta.tar.Z.
+
+2.5. Q. How stable is Python?
+
+A. Very stable.  While the current version number (0.9.9) would
+suggest it is in the early stages of development, in fact new, stable
+releases have been coming out every 3-6 months for the past three years.
+
+2.6. Q. Any more future plans?
+
+A. Without warranty that any of this will actually be realized: I am
+currently thinking about mechanisms for built-in on-line help and a
+switch/case statement.  There are also some people (independently)
+working on a windowing interface based on STDWIN but with the power
+and ease of use of the average modern widget set.  I still hope to get
+some help in producing a Windows version.  It would be nice if there
+were a window-based class browser (Someone at CWI has contributed one
+using Motif but it needs some work).
+
+
+3. Building Python
+==================
+
+3.1. Q. I have trouble building the md5 module and/or finding the file
+md5.c.
+
+A. Apparently the md5 module was based on an older version of RSA's
+md5 implementation.  The ftp site rsa.com mentioned in the Makefile
+where this version was found is no longer accessible, and the version
+from RFC 1321 (md5c.c) is slightly different.  This will be fixed in
+the 1.0 release; write me if you need the fixes now.
+
+3.2. Q. Is there a test set?
+
+A. Yes, simply do "import testall" (or "import autotest" if you aren't
+interested in the output).  The standard modules whose name begins
+with "test" together comprise the test.  The test set doesn't test
+*all* features of Python but it goes a long way to confirm that a new
+port is actually working.  The Makefile contains an entry "make test"
+which runs the autotest module.
+
+3.3. Q. When running the test set, I get complaints about floating point
+operations, but when playing with floating point operations I cannot
+find anything wrong with them.
+
+A. The test set makes occasional unwarranted assumptions about the
+semantics of C floating point operations.  Until someone donates a
+better floating point test set, you will have to comment out the
+offending floating point tests and execute similar tests manually.
+
+3.4. Q. I get an OverflowError on evaluating 2*2.  What is going on?
+
+A. Your machine probably has 64 bit long integers (e.g. DEC alpha or
+HP snake architectures).  There are some dependencies on word length
+in file intobject.c.  This will be corrected in the 1.0 release; until
+then, on a 64 bit machine, just comment out the check for overflow
+from int_mul:
+
+	#if 0
+		if (x > 0x7fffffff || x < (double) (long) 0x80000000)
+			return err_ovf("integer multiplication");
+	#endif
+
+You should also include <limits.h> and replace the constant 32 by
+LONG_BIT in int_[lr]shift.
+
+3.5. Q. Trouble building Python 0.9.9 on platform X.
+
+A. In the bootstrap phase (before you have built the first running
+interpreter), make sure the -D settings in the Makefile are correct
+for your system.  In particular you may have to add or delete -DSYSV.
+It may also be necessary to change the flags used to compile
+posixmodule.c and timemodule.c; e.g. on AIX the following are
+necessary:
+  posixmodule.c: -DHAVE_STDLIB -DNOALTTZ -DOLDTZ -Dunix -DSYSV -DDO_TIMES
+  timemodule.c:  -DHAVE_STDLIB -DNOALTTZ -DOLDTZ -Uunix -DSYSV -DBSD_TIME
+(Note the -Uunix for timemodule!)
+Those switches for timemodule also require that the 
+	#ifdef unix
+	#ifdef BSD_TIME
+just above:
+	static long
+	millitimer() 
+( and below the "#endif  /* macintosh */"  version of millitimer 
+be changed to:
+	#if defined(unix) | defined(BSD_TIME)
+	#ifdef BSD_TIME
+
+
+4. Programming in Python
+========================
+
+4.1. Q. Can I create an object class with some methods implemented in
+C and others in Python (e.g. through inheritance)?  (Also phrased as:
+Can I use a built-in type as base class?)
+
+A. No, but you can easily create a Python class which serves as a
+wrapper around a built-in object, e.g. (for dictionaries):
+
+	# A user-defined class behaving almost identical
+	# to a built-in dictionary.
+	class UserDict:
+		def __init__(self): self.data = {}
+		def __repr__(self): return repr(self.data)
+		def __cmp__(self, dict):
+			if type(dict) == type(self.data):
+				return cmp(self.data, dict)
+			else:
+				return cmp(self.data, dict.data)
+		def __len__(self): return len(self.data)
+		def __getitem__(self, key): return self.data[key]
+		def __setitem__(self, key, item): self.data[key] = item
+		def __delitem__(self, key): del self.data[key]
+		def keys(self): return self.data.keys()
+		def items(self): return self.data.items()
+		def values(self): return self.data.values()
+		def has_key(self, key): return self.data.has_key(key)
+
+4.2. Q. I assign to a variable in a call to exec() but when I try to
+use it on the next line I get an error.  What is going on?
+
+A. The reason why this occurs is too complicated to explain (but see
+the next question).  To fix it is easy, however: simply assign None to
+the variable *before* calling exec().  This will be fixed in the 1.0
+release.
+
+4.3. Q. Why does that work?
+
+A. When parsing your program and converting it into internal pseudo
+code, the interpreter does some optimizations to speed up function
+execution: it figures out the names of all the local variables and
+treats them specially.  Because your assignment is done by exec(), it
+is not seen initially by the parser and the variable is not recognized
+as a local variable.  The default treatment is as a global variable,
+but the exec() statement places it in the local scope, where it is not
+found.  This will be fixed in release 1.0 by making exec into a
+statement; the parser will then be able to switch off the
+optimizations for local variables if it encounters an exec statement
+(recognizing calls to built-in functions is not possible for the
+parser, hence the syntax change to a statement).
+
+4.4. Q. Is there a curses/termcap package for Python?
+
+A. No, but you can use the "alfa" (== character cell) version of
+STDWIN.  (STDWIN == Standard Windows, a portable windowing system
+interface by the same author, URL ftp://ftp.cwi.nl/pub/stdwin.)
+This will also prepare your program for porting to windowing
+environments such as X11 or the Macintosh.
+
+4.5. Q. Is there an equivalent to C's onexit() in Python?
+
+A. Yes, if you import sys and assign a function to sys.exitfunc, it
+will be called when your program exits, is killed by an unhandled
+exception, or (on UNIX) receives a SIGHUP or SIGTERM signal.
+
+4.6. Q. When I define a function nested inside another function, the
+nested function seemingly can't access the local variables of the
+outer function.  What is going on?  How do I pass local data to a
+nested function?
+
+A. Python does not have arbitrarily nested scopes.  When you need to
+create a function that needs to access some data which you have
+available locally, create a new class to hold the data and return a
+method of an instance of that class, e.g.:
+
+	class MultiplierClass:
+		def __init__(self, factor):
+			self.factor = factor
+		def multiplier(self, argument):
+			return argument * self.factor
+
+	def generate_multiplier(factor):
+		return MultiplierClass(factor).multiplier
+
+	twice = generate_multiplier(2)
+	print twice(10)
+	# Output: 20
+
+4.7. Q. How do I iterate over a sequence in reverse order?
+
+A. If it is a list, the fastest solution is
+
+	list.reverse()
+	try:
+		for x in list:
+			"do something with x"
+	finally:
+		list.reverse()
+
+This has the disadvantage that while you are in the loop, the list
+is temporarily reversed.  If you don't like this, you can make a copy.
+This appears expensive but is actually faster than other solutions:
+
+	rev = list[:]
+	rev.reverse()
+	for x in rev:
+		<do something with x>
+
+If it isn't a list, a more general but slower solution is:
+
+	i = len(list)
+	while i > 0:
+		i = i-1
+		x = list[i]
+		<do something with x>
+
+A more elegant solution, is to define a class which acts as a sequence
+and yields the elements in reverse order (solution due to Steve
+Majewski):
+
+	class Rev:
+		def __init__(self, seq):
+			self.forw = seq
+		def __len__(self):
+			return len(self.forw)
+		def __getitem__(self, i):
+			return self.forw[-(i + 1)]
+
+You can now simply write:
+
+	for x in Rev(list):
+		<do something with x>
+
+Unfortunately, this solution is slowest of all, due the the method
+call overhead...
+
+4.8. Q. My program is too slow.  How do I speed it up?
+
+A. That's a tough one, in general.  There are many tricks to speed up
+Python code; I would consider rewriting parts in C only as a last
+resort.  One thing to notice is that function and (especially) method
+calls are rather expensive; if you have designed a purely OO interface
+with lots of tiny functions that don't do much more than get or set an
+instance variable or call another method, you may consider using a
+more direct way, e.g. directly accessing instance variables.  Also see
+the standard module "profile" (described in the file
+"python/lib/profile.doc") which makes it possible to find out where
+your program is spending most of its time (if you have some patience
+-- the profiling itself can slow your program down by an order of
+magnitude).
+
+4.9. Q. When I have imported a module, then edit it, and import it
+again (into the same Python process), the changes don't seem to take
+place.  What is going on?
+
+A. For efficiency reasons, Python only reads the module file on the
+first time a module is imported (otherwise a program consisting of
+many modules, each of which imports the same basic module, would read
+the basic module over and over again).  To force a changed module
+being read again, do this:
+
+	import modname
+	reload(modname)
+
+Warning: this technique is not 100% fool-proof.  In particular,
+modules containing statements like
+
+	from modname import some_objects
+
+will continue to work with the old version of the objects imported
+thus.
+
+
+5. Extending Python
+===================
+
+5.1. Q. Can I create my own functions in C?
+
+A. Yes, you can create built-in modules containing functions,
+variables, exceptions and even new types in C.  This is all explained
+in the file "python/misc/EXTENDING".  Also read the file "DYNLOAD"
+there for hints on how to load such extension modules
+
+5.2. Q. Can I create my own functions in C++?
+
+A. Yes, using the C-compatibility features found in C++.  Basically
+you place extern "C" { ... } around the Python include files and put
+extern "C" before each function that is going to be called by the
+Python interpreter.  Global or static C++ objects with constructors
+are probably not a good idea.
+
+
+6. Python's design
+==================
+
+6.1. Q. Why isn't there a generic copying operation for objects in
+Python?
+
+A. Hmm.  Maybe there should be one, but it's difficult to assign a
+useful meaning to copying of open files, sockets and windows, or
+recursive data structures.  As long as you design all your classes
+yourself you are of course free to define a standard base class that
+defines an overridable copying operation for all the objects you care
+about.  (One practical point: it would have to be a built-in function,
+not a standard method name, since not all built-in object types have
+methods; e.g. strings, integers and tuples don't.)
+
+6.2. Q. Why isn't there a generic way to implement persistent objects
+in Python?  (Persistent == automatically saved to and restored from
+disk.)
+
+A. Hmm, hmm.  Basically for the same reasons as why there is no
+generic copying operation.
+
+6.3. Q. Why isn't there a switch or case statement in Python?
+
+A. You can do this easily enough with a sequence of
+if... elif... elif... else.  There have been some proposals for switch
+statement syntax, but there is no concensus (yet) on whether and how
+to do range tests.
+
+
+7. Using Python on non-UNIX platforms
+=====================================
+
+7.1. Q. Where's the DOS version of 0.9.9?
+
+A. I hope it will be coming soon.  A friend with a DOS machine and a
+compiler has volunteered to build it but he's very busy.  Until then,
+you will have to make do with the 0.9.8 version (which isn't so bad,
+actually).
+
+7.2. Q. Is there a Windows version of Python?
+
+A. Not yet.  Several Windows hackers with C compilers are working on a
+port though, so maybe we'll have one soon.
+
+7.3. Q. I have the Mac or DOS version but it appears to be only a binary.
+Where's the library?
+
+A. You still need to copy the files from the distribution directory
+"python/lib" to your system.  If you don't have the full distribution,
+you can ftp the file pythonlib0.9.9.tar.Z from site ftp.cwi.nl,
+directory /pub/python; this is a subset of the distribution containing
+just those file.
+
+7.4. Q. Where's the documentation for the Mac or DOS version?
+
+A. There isn't any.  The documentation for the Unix version also
+applies to the Mac and DOS versions.  Where applicable, differences
+are indicated in the text.
+
+7.5. Q. The Mac version doesn't seem to have any facilities for creating or
+editing programs apart from entering it interactively, and there seems
+to be no way to save code that was entered interactively.  How do I
+create a Python program on the Mac?
+
+A. Use an external editor.  I am quite happy with the Desk Accessory
+called Sigma Edit; this doesn't require Multifinder or System 7.  I
+work like this: start the interpreter; edit a module file using Sigma
+Edit; import and test it in the interpreter; edit again in Sigma Edit;
+then use the built-in function reload() to re-read the imported
+module; etc.

+Python history
+--------------
+
+This file contains the release messages for previous Python releases
+(slightly edited to adapt them to the format of this file).  As you
+read on you go back to the dark ages of Python's history.
+
+===================================
+==> Release 0.9.9 (29 Jul 1993) <==
+===================================
+
+I *believe* these are the main user-visible changes in this release,
+but there may be others.  SGI users may scan the {src,lib}/ChangeLog
+files for improvements of some SGI specific modules, e.g. aifc and
+cl.  Developers of extension modules should also read src/ChangeLog.
+
+
+Naming of C symbols used by the Python interpreter
+--------------------------------------------------
+
+* This is the last release using the current naming conventions.  New
+naming conventions are explained in the file misc/NAMING.
+Summarizing, all externally visible symbols get (at least) a "Py"
+prefix, and most functions are renamed to the standard form
+PyModule_FunctionName.
+
+* Writers of extensions are urged to start using the new naming
+conventions.  The next release will use the new naming conventions
+throughout (it will also have a different source directory
+structure).
+
+* As a result of the preliminary work for the great renaming, many
+functions that were accidentally global have been made static.
+
+
+BETA X11 support
+----------------
+
+* There are now modules interfacing to the X11 Toolkit Intrinsics, the
+Athena widgets, and the Motif 1.1 widget set.  These are not yet
+documented except through the examples and README file in the demo/x11
+directory.  It is expected that this interface will be replaced by a
+more powerful and correct one in the future, which may or may not be
+backward compatible.  In other words, this part of the code is at most
+BETA level software!  (Note: the rest of Python is rock solid as ever!)
+
+* I understand that the above may be a bit of a disappointment,
+however my current schedule does not allow me to change this situation
+before putting the release out of the door.  By releasing it
+undocumented and buggy, at least some of the (working!) demo programs,
+like itr (my Internet Talk Radio browser) become available to a larger
+audience.
+
+* There are also modules interfacing to SGI's "Glx" widget (a GL
+window wrapped in a widget) and to NCSA's "HTML" widget (which can
+format HyperText Markup Language, the document format used by the
+World Wide Web).
+
+* I've experienced some problems when building the X11 support.  In
+particular, the Xm and Xaw widget sets don't go together, and it
+appears that using X11R5 is better than using X11R4.  Also the threads
+module and its link time options may spoil things.  My own strategy is
+to build two Python binaries: one for use with X11 and one without
+it, which can contain a richer set of built-in modules.  Don't even
+*think* of loading the X11 modules dynamically...
+
+
+Environmental changes
+---------------------
+
+* Compiled files (*.pyc files) created by this Python version are
+incompatible with those created by the previous version.  Both
+versions detect this and silently create a correct version, but it
+means that it is not a good idea to use the same library directory for
+an old and a new interpreter, since they will start to "fight" over
+the *.pyc files...
+
+* When a stack trace is printed, the exception is printed last instead
+of first.  This means that if the beginning of the stack trace
+scrolled out of your window you can still see what exception caused
+it.
+
+* Sometimes interrupting a Python operation does not work because it
+hangs in a blocking system call.  You can now kill the interpreter by
+interrupting it three times.  The second time you interrupt it, a
+message will be printed telling you that the third interrupt will kill
+the interpreter.  The "sys.exitfunc" feature still makes limited
+clean-up possible in this case.
+
+
+Changes to the command line interface
+-------------------------------------
+
+* The python usage message is now much more informative.
+
+* New option -i enters interactive mode after executing a script --
+useful for debugging.
+
+* New option -k raises an exception when an expression statement
+yields a value other than None.
+
+* For each option there is now also a corresponding environment
+variable.
+
+
+Using Python as an embedded language
+------------------------------------
+
+* The distribution now contains (some) documentation on the use of
+Python as an "embedded language" in other applications, as well as a
+simple example.  See the file misc/EMBEDDING and the directory embed/.
+
+
+Speed improvements
+------------------
+
+* Function local variables are now generally stored in an array and
+accessed using an integer indexing operation, instead of through a
+dictionary lookup.  (This compensates the somewhat slower dictionary
+lookup caused by the generalization of the dictionary module.)
+
+
+Changes to the syntax
+---------------------
+
+* Continuation lines can now *sometimes* be written without a
+backslash: if the continuation is contained within nesting (), [] or
+{} brackets the \ may be omitted.  There's a much improved
+python-mode.el in the misc directory which knows about this as well.
+
+* You can no longer use an empty set of parentheses to define a class
+without base classes.  That is, you no longer write this:
+
+	class Foo(): # syntax error
+		...
+
+You must write this instead:
+
+	class Foo:
+		...
+
+This was already the preferred syntax in release 0.9.8 but many
+people seemed not to have picked it up.  There's a Python script that
+fixes old code: demo/scripts/classfix.py.
+
+* There's a new reserved word: "access".  The syntax and semantics are
+still subject of of research and debate (as well as undocumented), but
+the parser knows about the keyword so you must not use it as a
+variable, function, or attribute name.
+
+
+Changes to the semantics of the language proper
+-----------------------------------------------
+
+* The following compatibility hack is removed: if a function was
+defined with two or more arguments, and called with a single argument
+that was a tuple with just as many arguments, the items of this tuple
+would be used as the arguments.  This is no longer supported.
+
+
+Changes to the semantics of classes and instances
+-------------------------------------------------
+
+* Class variables are now also accessible as instance variables for
+reading (assignment creates an instance variable which overrides the
+class variable of the same name though).
+
+* If a class attribute is a user-defined function, a new kind of
+object is returned: an "unbound method".  This contains a pointer to
+the class and can only be called with a first argument which is a
+member of that class (or a derived class).
+
+* If a class defines a method __init__(self, arg1, ...) then this
+method is called when a class instance is created by the classname()
+construct.  Arguments passed to classname() are passed to the
+__init__() method.  The __init__() methods of base classes are not
+automatically called; the derived __init__() method must call these if
+necessary (this was done so the derived __init__() method can choose
+the call order and arguments for the base __init__() methods).
+
+* If a class defines a method __del__(self) then this method is called
+when an instance of the class is about to be destroyed.  This makes it
+possible to implement clean-up of external resources attached to the
+instance.  As with __init__(), the __del__() methods of base classes
+are not automatically called.  If __del__ manages to store a reference
+to the object somewhere, its destruction is postponed; when the object
+is again about to be destroyed its __del__() method will be called
+again.
+
+* Classes may define a method __hash__(self) to allow their instances
+to be used as dictionary keys.  This must return a 32-bit integer.
+
+
+Minor improvements
+------------------
+
+* Function and class objects now know their name (the name given in
+the 'def' or 'class' statement that created them).
+
+* Class instances now know their class name.
+
+
+Additions to built-in operations
+--------------------------------
+
+* The % operator with a string left argument implements formatting
+similar to sprintf() in C.  The right argument is either a single
+value or a tuple of values.  All features of Standard C sprintf() are
+supported except %p.
+
+* Dictionaries now support almost any key type, instead of just
+strings.  (The key type must be an immutable type or must be a class
+instance where the class defines a method __hash__(), in order to
+avoid losing track of keys whose value may change.)
+
+* Built-in methods are now compared properly: when comparing x.meth1
+and y.meth2, if x is equal to y and the methods are defined by the
+same function, x.meth1 compares equal to y.meth2.
+
+
+Additions to built-in functions
+-------------------------------
+
+* str(x) returns a string version of its argument.  If the argument is
+a string it is returned unchanged, otherwise it returns `x`.
+
+* repr(x) returns the same as `x`.  (Some users found it easier to
+have this as a function.)
+
+* round(x) returns the floating point number x rounded to an whole
+number, represented as a floating point number.  round(x, n) returns x
+rounded to n digits.
+
+* hasattr(x, name) returns true when x has an attribute with the given
+name.
+
+* hash(x) returns a hash code (32-bit integer) of an arbitrary
+immutable object's value.
+
+* id(x) returns a unique identifier (32-bit integer) of an arbitrary
+object.
+
+* compile() compiles a string to a Python code object.
+
+* exec() and eval() now support execution of code objects.
+
+
+Changes to the documented part of the library (standard modules)
+----------------------------------------------------------------
+
+* os.path.normpath() (a.k.a. posixpath.normpath()) has been fixed so
+the border case '/foo/..' returns '/' instead of ''.
+
+* A new function string.find() is added with similar semantics to
+string.index(); however when it does not find the given substring it
+returns -1 instead of raising string.index_error.
+
+
+Changes to built-in modules
+---------------------------
+
+* New optional module 'array' implements operations on sequences of
+integers or floating point numbers of a particular size.  This is
+useful to manipulate large numerical arrays or to read and write
+binary files consisting of numerical data.
+
+* Regular expression objects created by module regex now support a new
+method named group(), which returns one or more \(...\) groups by number.
+The number of groups is increased from 10 to 100.
+
+* Function compile() in module regex now supports an optional mapping
+argument; a variable casefold is added to the module which can be used
+as a standard uppercase to lowercase mapping.
+
+* Module time now supports many routines that are defined in the
+Standard C time interface (<time.h>): gmtime(), localtime(),
+asctime(), ctime(), mktime(), as well as these variables (taken from
+System V): timezone, altzone, daylight and tzname.  (The corresponding
+functions in the undocumented module calendar have been removed; the
+undocumented and unfinished module tzparse is now obsolete and will
+disappear in a future release.)
+
+* Module strop (the fast built-in version of standard module string)
+now uses C's definition of whitespace instead of fixing it to space,
+tab and newline; in practice this usually means that vertical tab,
+form feed and return are now also considered whitespace.  It exports
+the string of characters that are considered whitespace as well as the
+characters that are considered lowercase or uppercase.
+
+* Module sys now defines the variable builtin_module_names, a list of
+names of modules built into the current interpreter (including not
+yet imported, but excluding two special modules that always have to be
+defined -- sys and builtin).
+
+* Objects created by module sunaudiodev now also support flush() and
+close() methods.
+
+* Socket objects created by module socket now support an optional
+flags argument for their methods sendto() and recvfrom().
+
+* Module marshal now supports dumping to and loading from strings,
+through the functions dumps() and loads().
+
+* Module stdwin now supports some new functionality.  You may have to
+ftp the latest version: ftp.cwi.nl:/pub/stdwin/stdwinforviews.tar.Z.)
+
+
+Bugs fixed
+----------
+
+* Fixed comparison of negative long integers.
+
+* The tokenizer no longer botches input lines longer than BUFSIZ.
+
+* Fixed several severe memory leaks in module select.
+
+* Fixed memory leaks in modules socket and sv.
+
+* Fixed memory leak in divmod() for long integers.
+
+* Problems with definition of floatsleep() on Suns fixed.
+
+* Many portability bugs fixed (and undoubtedly new ones added :-).
+
+
+Changes to the build procedure
+------------------------------
+
+* The Makefile supports some new targets: "make default" and "make
+all".  Both are by normally equivalent to "make python".
+
+* The Makefile no longer uses $> since it's not supported by all
+versions of Make.
+
+* The header files now all contain #ifdef constructs designed to make
+it safe to include the same header file twice, as well as support for
+inclusion from C++ programs (automatic extern "C" { ... } added).
+
+
+Freezing Python scripts
+-----------------------
+
+* There is now some support for "freezing" a Python script as a
+stand-alone executable binary file.  See the script
+demo/scripts/freeze.py.  It will require some site-specific tailoring
+of the script to get this working, but is quite worthwhile if you write
+Python code for other who may not have built and installed Python.
+
+
+MS-DOS
+------
+
+* A new MS-DOS port has been done, using MSC 6.0 (I believe).  Thanks,
+Marcel van der Peijl!  This requires fewer compatibility hacks in
+posixmodule.c.  The executable is not yet available but will be soon
+(check the mailing list).
+
+* The default PYTHONPATH has changed.
+

+
+==================================
+==> Release 0.9.8 (9 Jan 1993) <==
+==================================
+
+I claim no completeness here, but I've tried my best to scan the log
+files throughout my source tree for interesting bits of news.  A more
+complete account of the changes is to be found in the various
+ChangeLog files. See also "News for release 0.9.7beta" below if you're
+still using release 0.9.6, and the file HISTORY if you have an even
+older release.
+
+	--Guido
+
+
+Changes to the language proper
+------------------------------
+
+There's only one big change: the conformance checking for function
+argument lists (of user-defined functions only) is stricter.  Earlier,
+you could get away with the following:
+
+	(a) define a function of one argument and call it with any
+	    number of arguments; if the actual argument count wasn't
+	    one, the function would receive a tuple containing the
+	    arguments arguments (an empty tuple if there were none).
+
+	(b) define a function of two arguments, and call it with more
+	    than two arguments; if there were more than two arguments,
+	    the second argument would be passed as a tuple containing
+	    the second and further actual arguments.
+
+(Note that an argument (formal or actual) that is a tuple is counted as
+one; these rules don't apply inside such tuples, only at the top level
+of the argument list.)
+
+Case (a) was needed to accommodate variable-length argument lists;
+there is now an explicit "varargs" feature (precede the last argument
+with a '*').  Case (b) was needed for compatibility with old class
+definitions: up to release 0.9.4 a method with more than one argument
+had to be declared as "def meth(self, (arg1, arg2, ...)): ...".
+Version 0.9.6 provide better ways to handle both casees, bot provided
+backward compatibility; version 0.9.8 retracts the compatibility hacks
+since they also cause confusing behavior if a function is called with
+the wrong number of arguments.
+
+There's a script that helps converting classes that still rely on (b),
+provided their methods' first argument is called "self":
+demo/scripts/methfix.py.
+
+If this change breaks lots of code you have developed locally, try
+#defining COMPAT_HACKS in ceval.c.
+
+(There's a third compatibility hack, which is the reverse of (a): if a
+function is defined with two or more arguments, and called with a
+single argument that is a tuple with just as many arguments, the items
+of this tuple will be used as the arguments.  Although this can (and
+should!) be done using the built-in function apply() instead, it isn't
+withdrawn yet.)
+
+
+One minor change: comparing instance methods works like expected, so
+that if x is an instance of a user-defined class and has a method m,
+then (x.m==x.m) yields 1.
+
+
+The following was already present in 0.9.7beta, but not explicitly
+mentioned in the NEWS file: user-defined classes can now define types
+that behave in almost allrespects like numbers.  See
+demo/classes/Rat.py for a simple example.
+
+
+Changes to the build process
+----------------------------
+
+The Configure.py script and the Makefile has been made somewhat more
+bullet-proof, after reports of (minor) trouble on certain platforms.
+
+There is now a script to patch Makefile and config.c to add a new
+optional built-in module: Addmodule.sh.  Read the script before using!
+
+Useing Addmodule.sh, all optional modules can now be configured at
+compile time using Configure.py, so there are no modules left that
+require dynamic loading.
+
+The Makefile has been fixed to make it easier to use with the VPATH
+feature of some Make versions (e.g. SunOS).
+
+
+Changes affecting portability
+-----------------------------
+
+Several minor portability problems have been solved, e.g. "malloc.h"
+has been renamed to "mymalloc.h", "strdup.c" is no longer used, and
+the system now tolerates malloc(0) returning 0.
+
+For dynamic loading on the SGI, Jack Jansen's dl 1.6 is now
+distributed with Python.  This solves several minor problems, in
+particular scripts invoked using #! can now use dynamic loading.
+
+
+Changes to the interpreter interface
+------------------------------------
+
+On popular demand, there's finally a "profile" feature for interactive
+use of the interpreter.  If the environment variable $PYTHONSTARTUP is
+set to the name of an existing file, Python statements in this file
+are executed when the interpreter is started in interactive mode.
+
+There is a new clean-up mechanism, complementing try...finally: if you
+assign a function object to sys.exitfunc, it will be called when
+Python exits or receives a SIGTERM or SIGHUP signal.
+
+The interpreter is now generally assumed to live in
+/usr/local/bin/python (as opposed to /usr/local/python).  The script
+demo/scripts/fixps.py will update old scripts in place (you can easily
+modify it to do other similar changes).
+
+Most I/O that uses sys.stdin/stdout/stderr will now use any object
+assigned to those names as long as the object supports readline() or
+write() methods.
+
+The parser stack has been increased to 500 to accommodate more
+complicated expressions (7 levels used to be the practical maximum,
+it's now about 38).
+
+The limit on the size of the *run-time* stack has completely been
+removed -- this means that tuple or list displays can contain any
+number of elements (formerly more than 50 would crash the
+interpreter). 
+
+
+Changes to existing built-in functions and methods
+--------------------------------------------------
+
+The built-in functions int(), long(), float(), oct() and hex() now
+also apply to class instalces that define corresponding methods
+(__int__ etc.).
+
+
+New built-in functions
+----------------------
+
+The new functions str() and repr() convert any object to a string.
+The function repr(x) is in all respects equivalent to `x` -- some
+people prefer a function for this.  The function str(x) does the same
+except if x is already a string -- then it returns x unchanged
+(repr(x) adds quotes and escapes "funny" characters as octal escapes).
+
+The new function cmp(x, y) returns -1 if x<y, 0 if x==y, 1 if x>y.
+
+
+Changes to general built-in modules
+-----------------------------------
+
+The time module's functions are more general: time() returns a
+floating point number and sleep() accepts one.  Their accuracies
+depends on the precision of the system clock.  Millisleep is no longer
+needed (although it still exists for now), but millitimer is still
+needed since on some systems wall clock time is only available with
+seconds precision, while a source of more precise time exists that
+isn't synchronized with the wall clock.  (On UNIX systems that support
+the BSD gettimeofday() function, time.time() is as time.millitimer().)
+
+The string representation of a file object now includes an address:
+'<file 'filename', mode 'r' at #######>' where ###### is a hex number
+(the object's address) to make it unique.
+
+New functions added to posix: nice(), setpgrp(), and if your system
+supports them: setsid(), setpgid(), tcgetpgrp(), tcsetpgrp().
+
+Improvements to the socket module: socket objects have new methods
+getpeername() and getsockname(), and the {get,set}sockopt methods can
+now get/set any kind of option using strings built with the new struct
+module.  And there's a new function fromfd() which creates a socket
+object given a file descriptor (useful for servers started by inetd,
+which have a socket connected to stdin and stdout).
+
+
+Changes to SGI-specific built-in modules
+----------------------------------------
+
+The FORMS library interface (fl) now requires FORMS 2.1a.  Some new
+functions have been added and some bugs have been fixed.
+
+Additions to al (audio library interface): added getname(),
+getdefault() and getminmax().
+
+The gl modules doesn't call "foreground()" when initialized (this
+caused some problems) like it dit in 0.9.7beta (but not before).
+There's a new gl function 'gversion() which returns a version string.
+
+The interface to sv (Indigo video interface) has totally changed.
+(Sorry, still no documentation, but see the examples in
+demo/sgi/{sv,video}.)
+
+
+Changes to standard library modules
+-----------------------------------
+
+Most functions in module string are now much faster: they're actually
+implemented in C.  The module containing the C versions is called
+"strop" but you should still import "string" since strop doesn't
+provide all the interfaces defined in string (and strop may be renamed
+to string when it is complete in a future release).
+
+string.index() now accepts an optional third argument giving an index
+where to start searching in the first argument, so you can find second
+and further occurrences (this is similar to the regular expression
+functions in regex).
+
+The definition of what string.splitfields(anything, '') should return
+is changed for the last time: it returns a singleton list containing
+its whole first argument unchanged.  This is compatible with
+regsub.split() which also ignores empty delimiter matches.
+
+posixpath, macpath: added dirname() and normpath() (and basename() to
+macpath).
+
+The mainloop module (for use with stdwin) can now demultiplex input
+from other sources, as long as they can be polled with select().
+
+
+New built-in modules
+--------------------
+
+Module struct defines functions to pack/unpack values to/from strings
+representing binary values in native byte order.
+
+Module strop implements C versions of many functions from string (see
+above).
+
+Optional module fcntl defines interfaces to fcntl() and ioctl() --
+UNIX only.  (Not yet properly documented -- see however src/fcntl.doc.)
+
+Optional module mpz defines an interface to an altaernative long
+integer implementation, the GNU MPZ library.
+
+Optional module md5 uses the GNU MPZ library to calculate MD5
+signatures of strings.
+
+There are also optional new modules specific to SGI machines: imageop
+defines some simple operations to images represented as strings; sv
+interfaces to the Indigo video board; cl interfaces to the (yet
+unreleased) compression library.
+
+
+New standard library modules
+----------------------------
+
+(Unfortunately the following modules are not all documented; read the
+sources to find out more about them!)
+
+autotest: run testall without showing any output unless it differs
+from the expected output
+
+bisect: use bisection to insert or find an item in a sorted list
+
+colorsys: defines conversions between various color systems (e.g. RGB
+<-> YUV)
+
+nntplib: a client interface to NNTP servers
+
+pipes: utility to construct pipeline from templates, e.g. for
+conversion from one file format to another using several utilities.
+
+regsub: contains three functions that are more or less compatible with
+awk functions of the same name: sub() and gsub() do string
+substitution, split() splits a string using a regular expression to
+define how separators are define.
+
+test_types: test operations on the built-in types of Python
+
+toaiff: convert various audio file formats to AIFF format
+
+tzparse: parse the TZ environment parameter (this may be less general
+than it could be, let me know if you fix it).
+
+(Note that the obsolete module "path" no longer exists.)
+
+
+New SGI-specific library modules
+--------------------------------
+
+CL: constants for use with the built-in compression library interface (cl)
+
+Queue: a multi-producer, multi-consumer queue class implemented for
+use with the built-in thread module
+
+SOCKET: constants for use with built-in module socket, e.g. to set/get
+socket options.  This is SGI-specific because the constants to be
+passed are system-dependent.  You can generate a version for your own
+system by running the script demo/scripts/h2py.py with
+/usr/include/sys/socket.h as input.
+
+cddb: interface to the database used the the CD player
+
+torgb: convert various image file types to rgb format (requires pbmplus)
+
+
+New demos
+---------
+
+There's an experimental interface to define Sun RPC clients and
+servers in demo/rpc.
+
+There's a collection of interfaces to WWW, WAIS and Gopher (both
+Python classes and program providing a user interface) in demo/www.
+This includes a program texi2html.py which converts texinfo files to
+HTML files (the format used hy WWW).
+
+The ibrowse demo has moved from demo/stdwin/ibrowse to demo/ibrowse.
+
+For SGI systems, there's a whole collection of programs and classes
+that make use of the Indigo video board in demo/sgi/{sv,video}.  This
+represents a significant amount of work that we're giving away!
+
+There are demos "rsa" and "md5test" that exercise the mpz and md5
+modules, respectively.  The rsa demo is a complete implementation of
+the RSA public-key cryptosystem!
+
+A bunch of games and examples submitted by Stoffel Erasmus have been
+included in demo/stoffel.
+
+There are miscellaneous new files in some existing demo
+subdirectories: classes/bitvec.py, scripts/{fixps,methfix}.py,
+sgi/al/cmpaf.py, sockets/{mcast,gopher}.py.
+
+There are also many minor changes to existing files, but I'm too lazy
+to run a diff and note the differences -- you can do this yourself if
+you save the old distribution's demos.  One highlight: the
+stdwin/python.py demo is much improved!
+
+
+Changes to the documentation
+----------------------------
+
+The LaTeX source for the library uses different macros to enable it to
+be converted to texinfo, and from there to INFO or HTML format so it
+can be browsed as a hypertext.  The net result is that you can now
+read the Python library documentation in Emacs info mode!
+
+
+Changes to the source code that affect C extension writers
+----------------------------------------------------------
+
+The function strdup() no longer exists (it was used only in one places
+and is somewhat of a a portability problem sice some systems have the
+same function in their C library.
+
+The functions NEW() and RENEW() allocate one spare byte to guard
+against a NULL return from malloc(0) being taken for an error, but
+this should not be relied upon.
+
+
+=========================
+==> Release 0.9.7beta <==
+=========================
+
+
+Changes to the language proper
+------------------------------
+
+User-defined classes can now implement operations invoked through
+special syntax, such as x[i] or `x` by defining methods named
+__getitem__(self, i) or __repr__(self), etc.
+
+
+Changes to the build process
+----------------------------
+
+Instead of extensive manual editing of the Makefile to select
+compile-time options, you can now run a Configure.py script.
+The Makefile as distributed builds a minimal interpreter sufficient to
+run Configure.py.  See also misc/BUILD
+
+The Makefile now includes more "utility" targets, e.g. install and
+tags/TAGS
+
+Using the provided strtod.c and strtol.c are now separate options, as
+on the Sun the provided strtod.c dumps core :-(
+
+The regex module is now an option chosen by the Makefile, since some
+(old) C compilers choke on regexpr.c
+
+
+Changes affecting portability
+-----------------------------
+
+You need STDWIN version 0.9.7 (released 30 June 1992) for the stdwin
+interface
+
+Dynamic loading is now supported for Sun (and other non-COFF systems)
+throug dld-3.2.3, as well as for SGI (a new version of Jack Jansen's
+DL is out, 1.4)
+
+The system-dependent code for the use of the select() system call is
+moved to one file: myselect.h
+
+Thanks to Jaap Vermeulen, the code should now port cleanly to the
+SEQUENT
+
+
+Changes to the interpreter interface
+------------------------------------
+
+The interpretation of $PYTHONPATH in the environment is different: it
+is inserted in front of the default path instead of overriding it
+
+
+Changes to existing built-in functions and methods
+--------------------------------------------------
+
+List objects now support an optional argument to their sort() method,
+which is a comparison function similar to qsort(3) in C
+
+File objects now have a method fileno(), used by the new select module
+(see below)
+
+
+New built-in function
+---------------------
+
+coerce(x, y): take two numbers and return a tuple containing them
+both converted to a common type
+
+
+Changes to built-in modules
+---------------------------
+
+sys: fixed core dumps in settrace() and setprofile()
+
+socket: added socket methods setsockopt() and getsockopt(); and
+fileno(), used by the new select module (see below)
+
+stdwin: added fileno() == connectionnumber(), in support of new module
+select (see below)
+
+posix: added get{eg,eu,g,u}id(); waitpid() is now a separate function.
+
+gl: added qgetfd()
+
+fl: added several new functions, fixed several obscure bugs, adapted
+to FORMS 2.1
+
+
+Changes to standard modules
+---------------------------
+
+posixpath: changed implementation of ismount()
+
+string: atoi() no longer mistakes leading zero for octal number
+
+...
+
+
+New built-in modules
+--------------------
+
+Modules marked "dynamic only" are not configured at compile time but
+can be loaded dynamically.  You need to turn on the DL or DLD option in
+the Makefile for support dynamic loading of modules (this requires
+external code).
+
+select: interfaces to the BSD select() system call
+
+dbm: interfaces to the (new) dbm library (dynamic only)
+
+nis: interfaces to some NIS functions (aka yellow pages)
+
+thread: limited form of multiple threads (sgi only)
+
+audioop: operations useful for audio programs, e.g. u-LAW and ADPCM
+coding (dynamic only)
+
+cd: interface to Indigo SCSI CDROM player audio library (sgi only)
+
+jpeg: read files in JPEG format (dynamic only, sgi only; needs
+external code)
+
+imgfile: read SGI image files (dynamic only, sgi only)
+
+sunaudiodev: interface to sun's /dev/audio (dynamic only, sun only)
+
+sv: interface to Indigo video library (sgi only)
+
+pc: a minimal set of MS-DOS interfaces (MS-DOS only)
+
+rotor: encryption, by Lance Ellinghouse (dynamic only)
+
+
+New standard modules
+--------------------
+
+Not all these modules are documented.  Read the source:
+lib/<modulename>.py.  Sometimes a file lib/<modulename>.doc contains
+additional documentation.
+
+imghdr: recognizes image file headers
+
+sndhdr: recognizes sound file headers
+
+profile: print run-time statistics of Python code
+
+readcd, cdplayer: companion modules for built-in module cd (sgi only)
+
+emacs: interface to Emacs using py-connect.el (see below).
+
+SOCKET: symbolic constant definitions for socket options
+
+SUNAUDIODEV: symbolic constant definitions for sunaudiodef (sun only)
+
+SV: symbolic constat definitions for sv (sgi only)
+
+CD: symbolic constat definitions for cd (sgi only)
+
+
+New demos
+---------
+
+scripts/pp.py: execute Python as a filter with a Perl-like command
+line interface
+
+classes/: examples using the new class features
+
+threads/: examples using the new thread module
+
+sgi/cd/: examples using the new cd module
+
+
+Changes to the documentation
+----------------------------
+
+The last-minute syntax changes of release 0.9.6 are now reflected
+everywhere in the manuals
+
+The reference manual has a new section (3.2) on implementing new kinds
+of numbers, sequences or mappings with user classes
+
+Classes are now treated extensively in the tutorial (chapter 9)
+
+Slightly restructured the system-dependent chapters of the library
+manual
+
+The file misc/EXTENDING incorporates documentation for mkvalue() and
+a new section on error handling
+
+The files misc/CLASSES and misc/ERRORS are no longer necessary
+
+The doc/Makefile now creates PostScript files automatically
+
+
+Miscellaneous changes
+---------------------
+
+Incorporated Tim Peters' changes to python-mode.el, it's now version
+1.06
+
+A python/Emacs bridge (provided by Terrence M. Brannon) lets a Python
+program running in an Emacs buffer execute Emacs lisp code.  The
+necessary Python code is in lib/emacs.py.  The Emacs code is
+misc/py-connect.el (it needs some external Emacs lisp code)
+
+
+Changes to the source code that affect C extension writers
+----------------------------------------------------------
+
+New service function mkvalue() to construct a Python object from C
+values according to a "format" string a la getargs()
+
+Most functions from pythonmain.c moved to new pythonrun.c which is
+in libpython.a.  This should make embedded versions of Python easier
+
+ceval.h is split in eval.h (which needs compile.h and only declares
+eval_code) and ceval.h (which doesn't need compile.hand declares the
+rest)
+
+ceval.h defines macros BGN_SAVE / END_SAVE for use with threads (to
+improve the parallellism of multi-threaded programs by letting other
+Python code run when a blocking system call or something similar is
+made)
+
+In structmember.[ch], new member types BYTE, CHAR and unsigned
+variants have been added
+
+New file xxmodule.c is a template for new extension modules.

+  as a-(a/b)*b.  So now the outcome of divmod(a,b) is the same as
+  (a/b, a%b) for integers.  For floats, % is also changed, but of course
+  / is unchanged, and divmod(x,y) does not yield (x/y, x%y)...
+- A function with explicit variable-length argument list can be declared
+  like this: def f(*args): ...; or even like this: def f(a, b, *rest): ...
+- Code tracing and profiling features have been added, and two source
+  code debuggers are provided in the library (pdb.py, tty-oriented,
+  and wdb, window-oriented); you can now step through Python programs!
+  See sys.settrace() and sys.setprofile(), and "../lib/pdb.doc"
+- '==' is now the only equality operator; "../demo/scripts/eqfix.py" is
+  a script that fixes old Python modules
+- Plain integer right shift now uses sign extension
+- Long integer shift/mask operations now simulate 2's complement
+  to give more useful results for negative operands
+- Changed/added range checks for long/plain integer shifts
+- Options found after "-c command" are now passed to the command in sys.argv
+  (note subtle incompatiblity with "python -c command -- -options"!)
+- Module stdwin is better protected against touching objects after they've
+  been closed; menus can now also be closed explicitly
+- Stdwin now uses its own exception (stdwin.error)
+
+New features in 0.9.5 (released as Macintosh application only, 2 Jan 1992):
+- dictionary objects can now be compared properly; e.g., {}=={} is true
+- new exception SystemExit causes termination if not caught;
+  it is raised by sys.exit() so that 'finally' clauses can clean up,
+  and it may even be caught.  It does work interactively!
+- new module "regex" implements GNU Emacs style regular expressions;
+  module "regexp" is rewritten in Python for backward compatibility
+- formal parameter lists may contain trailing commas
+
+Bugs fixed in 0.9.6:
+- assigning to or deleting a list item with a negative index dumped core
+- divmod(-10L,5L) returned (-3L, 5L) instead of (-2L, 0L)
+
+Bugs fixed in 0.9.5:
+- masking operations involving negative long integers gave wrong results
+
+
+===================================
+==> RELEASE 0.9.4 (24 Dec 1991) <==
+===================================
+
+- new function argument handling (see below)
+- built-in apply(func, args) means func(args[0], args[1], ...)
+- new, more refined exceptions
+- new exception string values (NameError = 'NameError' etc.)
+- better checking for math exceptions
+- for sequences (string/tuple/list), x[-i] is now equivalent to x[len(x)-i]
+- fixed list assignment bug: "a[1:1] = a" now works correctly
+- new class syntax, without extraneous parentheses
+- new 'global' statement to assign global variables from within a function
+
+
+New class syntax
+----------------
+
+You can now declare a base class as follows:
+
+	class B:			# Was: class B():
+		def some_method(self): ...
+		...
+
+and a derived class thusly:
+
+	class D(B):			# Was: class D() = B():
+		def another_method(self, arg): ...
+
+Multiple inheritance looks like this:
+
+	class M(B, D):			# Was: class M() = B(), D():
+		def this_or_that_method(self, arg): ...
+
+The old syntax is still accepted by Python 0.9.4, but will disappear
+in Python 1.0 (to be posted to comp.sources).
+
+
+New 'global' statement
+----------------------
+
+Every now and then you have a global variable in a module that you
+want to change from within a function in that module -- say, a count
+of calls to a function, or an option flag, etc.  Until now this was
+not directly possible.  While several kludges are known that
+circumvent the problem, and often the need for a global variable can
+be avoided by rewriting the module as a class, this does not always
+lead to clearer code.
+
+The 'global' statement solves this dilemma.  Its occurrence in a
+function body means that, for the duration of that function, the
+names listed there refer to global variables.  For instance:
+
+	total = 0.0
+	count = 0
+
+	def add_to_total(amount):
+		global total, count
+		total = total + amount
+		count = count + 1
+
+'global' must be repeated in each function where it is needed.  The
+names listed in a 'global' statement must not be used in the function
+before the statement is reached.
+
+Remember that you don't need to use 'global' if you only want to *use*
+a global variable in a function; nor do you need ot for assignments to
+parts of global variables (e.g., list or dictionary items or
+attributes of class instances).  This has not changed; in fact
+assignment to part of a global variable was the standard workaround.
+
+
+New exceptions
+--------------
+
+Several new exceptions have been defined, to distinguish more clearly
+between different types of errors.
+
+name			meaning					was
+
+AttributeError		reference to non-existing attribute	NameError
+IOError			unexpected I/O error			RuntimeError
+ImportError		import of non-existing module or name	NameError
+IndexError		invalid string, tuple or list index	RuntimeError
+KeyError		key not in dictionary			RuntimeError
+OverflowError		numeric overflow			RuntimeError
+SyntaxError		invalid syntax				RuntimeError
+ValueError		invalid argument value			RuntimeError
+ZeroDivisionError	division by zero			RuntimeError
+
+The string value of each exception is now its name -- this makes it
+easier to experimentally find out which operations raise which
+exceptions; e.g.:
+
+	>>> KeyboardInterrupt
+	'KeyboardInterrupt'
+	>>>
+
+
+New argument passing semantics
+------------------------------
+
+Off-line discussions with Steve Majewski and Daniel LaLiberte have
+convinced me that Python's parameter mechanism could be changed in a
+way that made both of them happy (I hope), kept me happy, fixed a
+number of outstanding problems, and, given some backward compatibility
+provisions, would only break a very small amount of existing code --
+probably all mine anyway.  In fact I suspect that most Python users
+will hardly notice the difference.  And yet it has cost me at least
+one sleepless night to decide to make the change...
+
+Philosophically, the change is quite radical (to me, anyway): a
+function is no longer called with either zero or one argument, which
+is a tuple if there appear to be more arguments.  Every function now
+has an argument list containing 0, 1 or more arguments.  This list is
+always implemented as a tuple, and it is a (run-time) error if a
+function is called with a different number of arguments than expected.
+
+What's the difference? you may ask.  The answer is, very little unless
+you want to write variadic functions -- functions that may be called
+with a variable number of arguments.  Formerly, you could write a
+function that accepted one or more arguments with little trouble, but
+writing a function that could be called with either 0 or 1 argument
+(or more) was next to impossible.  This is now a piece of cake: you
+can simply declare an argument that receives the entire argument
+tuple, and check its length -- it will be of size 0 if there are no
+arguments.
+
+Another anomaly of the old system was the way multi-argument methods
+(in classes) had to be declared, e.g.:
+
+	class Point():
+		def init(self, (x, y, color)): ...
+		def setcolor(self, color): ...
+		dev moveto(self, (x, y)): ...
+		def draw(self): ...
+
+Using the new scheme there is no need to enclose the method arguments
+in an extra set of parentheses, so the above class could become:
+
+	class Point:
+		def init(self, x, y, color): ...
+		def setcolor(self, color): ...
+		dev moveto(self, x, y): ...
+		def draw(self): ...
+
+That is, the equivalence rule between methods and functions has
+changed so that now p.moveto(x,y) is equivalent to Point.moveto(p,x,y)
+while formerly it was equivalent to Point.moveto(p,(x,y)).
+
+A special backward compatibility rule makes that the old version also
+still works: whenever a function with exactly two arguments (at the top
+level) is called with more than two arguments, the second and further
+arguments are packed into a tuple and passed as the second argument.
+This rule is invoked independently of whether the function is actually a
+method, so there is a slight chance that some erroneous calls of
+functions expecting two arguments with more than that number of
+arguments go undetected at first -- when the function tries to use the
+second argument it may find it is a tuple instead of what was expected.
+Note that this rule will be removed from future versions of the
+language; it is a backward compatibility provision *only*.
+
+Two other rules and a new built-in function handle conversion between
+tuples and argument lists:
+
+Rule (a): when a function with more than one argument is called with a
+single argument that is a tuple of the right size, the tuple's items
+are used as arguments.
+
+Rule (b): when a function with exactly one argument receives no
+arguments or more than one, that one argument will receive a tuple
+containing the arguments (the tuple will be empty if there were no
+arguments).
+
+
+A new built-in function, apply(), was added to support functions that
+need to call other functions with a constructed argument list.  The call
+
+	apply(function, tuple)
+
+is equivalent to
+
+	function(tuple[0], tuple[1], ..., tuple[len(tuple)-1])
+
+
+While no new argument syntax was added in this phase, it would now be
+quite sensible to add explicit syntax to Python for default argument
+values (as in C++ or Modula-3), or a "rest" argument to receive the
+remaining arguments of a variable-length argument list.

+
+Extended list of changes in 0.9.2
+---------------------------------
+
+Here is a summary of the most important user-visible changes in 0.9.2,
+in somewhat arbitrary order.  Changes in later versions are listed in
+the "highlights" section above.
+
+
+1. Changes to the interpreter proper
+
+- Simple statements can now be separated by semicolons.
+  If you write "if t: s1; s2", both s1 and s2 are executed
+  conditionally.
+- The 'continue' statement was added, with semantics as in C.
+- Dictionary displays are now allowed on input: {key: value, ...}.
+- Blank lines and lines bearing only a comment no longer need to
+  be indented properly.  (A completely empty line still ends a multi-
+  line statement interactively.)
+- Mixed arithmetic is supported, 1 compares equal to 1.0, etc.
+- Option "-c command" to execute statements from the command line
+- Compiled versions of modules are cached in ".pyc" files, giving a
+  dramatic improvement of start-up time
+- Other, smaller speed improvements, e.g., extracting characters from
+  strings, looking up single-character keys, and looking up global
+  variables
+- Interrupting a print operation raises KeyboardInterrupt instead of
+  only cancelling the print operation
+- Fixed various portability problems (it now passes gcc with only
+  warnings -- more Standard C compatibility will be provided in later
+  versions)
+- Source is prepared for porting to MS-DOS
+- Numeric constants are now checked for overflow (this requires
+  standard-conforming strtol() and strtod() functions; a correct
+  strtol() implementation is provided, but the strtod() provided
+  relies on atof() for everything, including error checking
+
+
+2. Changes to the built-in types, functions and modules
+
+- New module socket: interface to BSD socket primitives
+- New modules pwd and grp: access the UNIX password and group databases
+- (SGI only:) New module "fm" interfaces to the SGI IRIX Font Manager
+- (SGI only:) New module "fl" interfaces to Mark Overmars' FORMS library
+- New numeric type: long integer, for unlimited precision
+	- integer constants suffixed with 'L' or 'l' are long integers
+	- new built-in function long(x) converts int or float to long
+	- int() and float() now also convert from long integers
+- New built-in function:
+	- pow(x, y) returns x to the power y
+- New operation and methods for lists:
+	- l*n returns a new list consisting of n concatenated copies of l
+	- l.remove(x) removes the first occurrence of the value x from l
+	- l.index(x) returns the index of the first occurrence of x in l
+	- l.reverse() reverses l in place
+- New operation for tuples:
+	- t*n returns a tuple consisting of n concatenated copies of t
+- Improved file handling:
+	- f.readline() no longer restricts the line length, is faster,
+	  and isn't confused by null bytes; same for raw_input()
+	- f.read() without arguments reads the entire (rest of the) file
+	- mixing of print and sys.stdout.write() has different effect
+- New methods for files:
+	- f.readlines() returns a list containing the lines of the file,
+	  as read with f.readline()
+	- f.flush(), f.tell(), f.seek() call their stdio counterparts
+	- f.isatty() tests for "tty-ness"
+- New posix functions:
+	- _exit(), exec(), fork(), getpid(), getppid(), kill(), wait()
+	- popen() returns a file object connected to a pipe
+	- utime() replaces utimes() (the latter is not a POSIX name)
+- New stdwin features, including:
+	- font handling
+	- color drawing
+	- scroll bars made optional
+	- polygons
+	- filled and xor shapes
+	- text editing objects now have a 'settext' method
+
+
+3. Changes to the standard library
+
+- Name change: the functions path.cat and macpath.cat are now called
+  path.join and macpath.join
+- Added new modules: formatter, mutex, persist, sched, mainloop
+- Added some modules and functionality to the "widget set" (which is
+  still under development, so please bear with me):
+	DirList, FormSplit, TextEdit, WindowSched
+- Fixed module testall to work non-interactively
+- Module string:
+	- added functions join() and joinfields()
+	- fixed center() to work correct and make it "transitive"
+- Obsolete modules were removed: util, minmax
+- Some modules were moved to the demo directory
+
+
+4. Changes to the demonstration programs
+
+- Added new useful scipts: byteyears, eptags, fact, from, lfact,
+  objgraph, pdeps, pi, primes, ptags, which
+- Added a bunch of socket demos
+- Doubled the speed of ptags
+- Added new stdwin demos: microedit, miniedit
+- Added a windowing interface to the Python interpreter: python (most
+  useful on the Mac)
+- Added a browser for Emacs info files: demo/stdwin/ibrowse
+  (yes, I plan to put all STDWIN and Python documentation in texinfo
+  form in the future)
+
+
+5. Other changes to the distribution
+
+- An Emacs Lisp file "python.el" is provided to facilitate editing
+  Python programs in GNU Emacs (slightly improved since posted to
+  gnu.emacs.sources)
+- Some info on writing an extension in C is provided
+- Some info on building Python on non-UNIX platforms is provided
+

+To:  python-list
+Subject: comp.lang.python RFD again
+From: Guido.van.Rossum@cwi.nl
+
+I've followed the recent discussion and trimmed the blurb RFD down a bit
+(and added the word "object-oriented" to the blurb).
+
+I don't think it's too early to *try* to create the newsgroup --
+whether we will succeed may depend on how many Python supporters there
+are outside the mailing list.
+
+I'm personally not worried about moderation, and anyway I haven't
+heard from any volunteers for moderation (and I won't volunteer
+myself) so I suggest that we'll continue to ask for one unmoderated
+newsgroup.
+
+My next action will be to post an updated FAQ (which will hint at the
+upcoming RFD) to comp.lang.misc; then finalize the 1.0.0 release and
+put it on the ftp site.  I'll also try to get it into
+comp.sources.unix or .misc.  And all this before the end of January!
+
+--Guido van Rossum, CWI, Amsterdam <Guido.van.Rossum@cwi.nl>
+URL:  <http://www.cwi.nl/cwi/people/Guido.van.Rossum.html>
+
+======================================================================
+
+These are the steps required (in case you don't know about the
+newsgroup creation process):
+
+First, we need to draw up an RFD (Request For Discussion).  This is a
+document that tells what the purpose of the group is, and gives a case
+for its creation.  We post this to relevant groups (comp.lang.misc,
+the mailing list, news.groups, etc.)  Discussion is held on
+news.groups.
+
+Then, after a few weeks, we run the official CFV (Call For Votes).
+The votes are then collected over a period of weeks.  We need 100 more
+yes votes than no votes, and a 2/3 majority, to get the group.
+
+There are some restrictions on the vote taker: [s]he cannot actively
+campaign for/against the group during the vote process.  So the main
+benefit to Steve instead of me running the vote is that I will be free
+to campaign for its creation!
+
+The following is our current draft for the RFD.
+
+======================================================================
+
+Request For Discussion: comp.lang.python
+
+
+Purpose
+-------
+
+The newsgroup will be for discussion on the Python computer language.
+Possible topics include requests for information, general programming,
+development, and bug reports. The group will be unmoderated.
+
+
+What is Python?
+---------------
+
+Python is a relatively new very-high-level language developed in
+Amsterdam.  Python is a simple, object-oriented procedural language,
+with features taken from ABC, Icon, Modula-3, and C/C++.
+
+Its central goal is to provide the best of both worlds: the dynamic
+nature of scripting languages like Perl/TCL/REXX, but also support for
+general programming found in the more traditional languages like Icon,
+C, Modula,...
+
+Python may be FTP'd from the following sites:
+
+	ftp.cwi.nl in directory /pub/python (its "home site", also has a FAQ)
+	ftp.uu.net in directory /languages/python
+	gatekeeper.dec.com in directory /pub/plan/python/cwi
+
+
+Rationale
+---------
+
+Currently there is a mailing list with over 130 subscribers.
+The activity of this list is high, and to make handling the
+traffic more reasonable, a newsgroup is being proposed. We
+also feel that comp.lang.misc would not be a suitable forum
+for this volume of discussion on a particular language.
+
+
+Charter
+-------
+
+Comp.lang.python is an unmoderated newsgroup which will serve
+as a forum for discussing the Python computer language. The
+group will serve both those who just program in Python and
+those who work on developing the language. Topics that
+may be discussed include:
+
+	- announcements of new versions of the language and
+	  applications written in Python.
+
+	- discussion on the internals of the Python language.
+
+	- general information about the language.
+
+	- discussion on programming in Python.
+
+
+Discussion
+----------
+
+Any objections to this RFD will be considered and, if determined
+to be appropriate, will be incorporated. The discussion period
+will be for a period of 21 days after which the first CFV will be
+issued.

+  "*Indentation (in addition to py-indent-offset) for continued lines.
+The additional indentation given to the first continuation line in a
+multi-line statement.  Each subsequent continuation line in the
+statement inherits its indentation from the line that precedes it, so if

+This should follow the convention for non-indenting comment lines so

+should be of the form `#x...' where `x' is not a blank or a tab, and
+`...' is arbitrary).")
+
+(defvar py-scroll-process-buffer t
+  "*Scroll Python process buffer as output arrives.
+If nil, the Python process buffer acts, with respect to scrolling, like
+Shell-mode buffers normally act.  This is surprisingly complicated and
+so won't be explained here; in fact, you can't get the whole story
+without studying the Emacs C code.
+
+If non-nil, the behavior is different in two respects (which are
+slightly inaccurate in the interest of brevity):
+
+  - If the buffer is in a window, and you left point at its end, the
+    window will scroll as new output arrives, and point will move to the
+    buffer's end, even if the window is not the selected window (that
+    being the one the cursor is in).  The usual behavior for shell-mode
+    windows is not to scroll, and to leave point where it was, if the
+    buffer is in a window other than the selected window.
+
+  - If the buffer is not visible in any window, and you left point at
+    its end, the buffer will be popped into a window as soon as more
+    output arrives.  This is handy if you have a long-running
+    computation and don't want to tie up screen area waiting for the
+    output.  The usual behavior for a shell-mode buffer is to stay
+    invisible until you explicitly visit it.
+
+Note the `and if you left point at its end' clauses in both of the
+above:  you can `turn off' the special behaviors while output is in
+progress, by visiting the Python buffer and moving point to anywhere
+besides the end.  Then the buffer won't scroll, point will remain where
+you leave it, and if you hide the buffer it will stay hidden until you
+visit it again.  You can enable and disable the special behaviors as
+often as you like, while output is in progress, by (respectively) moving
+point to, or away from, the end of the buffer.
+
+Warning:  If you expect a large amount of output, you'll probably be
+happier setting this option to nil.
+
+Obscure:  `End of buffer' above should really say `at or beyond the
+process mark', but if you know what that means you didn't need to be
+told <grin>.")

+and send the code to a *Python* process via `\\[py-execute-buffer]' instead.
+
+Following are subtleties to note when using a *Python* process:
+
+If a *Python* process is used, the region is copied into a temp file (in
+directory py-temp-directory), and an `execfile' command is sent to
+Python naming that file.  If you send regions faster than Python can
+execute them, Python mode will save them into distinct temp files, and
+execute the next one in the queue the next time it sees a `>>> ' prompt
+from Python.  Each time this happens, the process buffer is popped into

+%v:py-python-command
+%v:py-scroll-process-buffer
+%v:py-temp-directory
+%v:py-beep-if-tab-change
+
+@KINDS OF LINES
+
+Each physical line in the file is either a `continuation line' (the
+preceding line ends with a backslash that's not part of a comment, or the
+paren/bracket/brace nesting level at the start of the line is non-zero,
+or both) or an `initial line' (everything else).
+
+An initial line is in turn a `blank line' (contains nothing except
+possibly blanks or tabs), a `comment line' (leftmost non-blank character
+is `#'), or a `code line' (everything else).
+
+Comment Lines
+
+Although all comment lines are treated alike by Python, Python mode
+recognizes two kinds that act differently with respect to indentation.
+
+An `indenting comment line' is a comment line with a blank, tab or
+nothing after the initial `#'.  The indentation commands (see below)
+treat these exactly as if they were code lines:  a line following an
+indenting comment line will be indented like the comment line.  All
+other comment lines (those with a non-whitespace character immediately
+following the initial `#') are `non-indenting comment lines', and their
+indentation is ignored by the indentation commands.
+
+Indenting comment lines are by far the usual case, and should be used
+whenever possible.  Non-indenting comment lines are useful in cases like
+these:
+
+\ta = b   # a very wordy single-line comment that ends up being
+\t        #... continued onto another line
+
+\tif a == b:
+##\t\tprint 'panic!' # old code we've `commented out'
+\t\treturn a
+
+Since the `#...' and `##' comment lines have a non-whitespace character
+following the initial `#', Python mode ignores them when computing the
+proper indentation for the next line.
+
+Continuation Lines and Statements
+
+The Python-mode commands generally work on statements instead of on
+individual lines, where a `statement' is a comment or blank line, or a
+code line and all of its following continuation lines (if any)
+considered as a single logical unit.  The commands in this mode
+generally (when it makes sense) automatically move to the start of the
+statement containing point, even if point happens to be in the middle of
+some continuation line.
+
+A Bad Idea
+
+Always put something on the initial line of a multi-line statement
+besides the backslash!  E.g., don't do this:
+
+\t\\
+\ta = b # what's the indentation of this stmt?
+
+While that's legal Python, it's silly & would be very expensive for
+Python mode to handle correctly.
+
+@INDENTATION
+
+Primarily for entering new code:
+\t\\[indent-for-tab-command]\t indent line appropriately
+\t\\[py-newline-and-indent]\t insert newline, then indent
+\t\\[py-delete-char]\t reduce indentation, or delete single character
+
+Primarily for reindenting existing code:
+\t\\[py-guess-indent-offset]\t guess py-indent-offset from file content; change locally
+\t\\[universal-argument] \\[py-guess-indent-offset]\t ditto, but change globally
+
+\t\\[py-indent-region]\t reindent region to match its context
+\t\\[py-shift-region-left]\t shift region left by py-indent-offset
+\t\\[py-shift-region-right]\t shift region right by py-indent-offset
+
+Unlike most programming languages, Python uses indentation, and only
+indentation, to specify block structure.  Hence the indentation supplied
+automatically by Python-mode is just an educated guess:  only you know
+the block structure you intend, so only you can supply correct
+indentation.
+
+The \\[indent-for-tab-command] and \\[py-newline-and-indent] keys try to suggest plausible indentation, based on
+the indentation of preceding statements.  E.g., assuming
+py-indent-offset is 4, after you enter
+\tif a > 0: \\[py-newline-and-indent]
+the cursor will be moved to the position of the `_' (_ is not a
+character in the file, it's just used here to indicate the location of
+the cursor):
+\tif a > 0:
+\t    _
+If you then enter `c = d' \\[py-newline-and-indent], the cursor will move
+to
+\tif a > 0:
+\t    c = d
+\t    _
+Python-mode cannot know whether that's what you intended, or whether
+\tif a > 0:
+\t    c = d
+\t_
+was your intent.  In general, Python-mode either reproduces the
+indentation of the (closest code or indenting-comment) preceding
+statement, or adds an extra py-indent-offset blanks if the preceding
+statement has `:' as its last significant (non-whitespace and non-
+comment) character.  If the suggested indentation is too much, use
+\\[py-delete-char] to reduce it.
+
+Warning:  indent-region should not normally be used!  It calls \\[indent-for-tab-command]
+repeatedly, and as explained above, \\[indent-for-tab-command] can't guess the block
+structure you intend.
+%c:indent-for-tab-command
+%c:py-newline-and-indent
+%c:py-delete-char
+
+
+The next function may be handy when editing code you didn't write:
+%c:py-guess-indent-offset
+
+
+The remaining `indent' functions apply to a region of Python code.  They
+assume the block structure (equals indentation, in Python) of the region
+is correct, and alter the indentation in various ways while preserving
+the block structure:
+%c:py-indent-region
+%c:py-shift-region-left
+%c:py-shift-region-right
+
+@MARKING & MANIPULATING REGIONS OF CODE
+
+\\[py-mark-block]\t mark block of lines
+\\[mark-python-def-or-class]\t mark smallest enclosing def
+\\[universal-argument] \\[mark-python-def-or-class]\t mark smallest enclosing class
+\\[py-comment-region]\t comment out region of code
+\\[universal-argument] \\[py-comment-region]\t uncomment region of code
+%c:py-mark-block
+%c:mark-python-def-or-class
+%c:py-comment-region
+
+@MOVING POINT
+
+\\[py-previous-statement]\t move to statement preceding point
+\\[py-next-statement]\t move to statement following point
+\\[py-goto-block-up]\t move up to start of current block
+\\[beginning-of-python-def-or-class]\t move to start of def
+\\[universal-argument] \\[beginning-of-python-def-or-class]\t move to start of class
+\\[end-of-python-def-or-class]\t move to end of def
+\\[universal-argument] \\[end-of-python-def-or-class]\t move to end of class
+
+The first two move to one statement beyond the statement that contains
+point.  A numeric prefix argument tells them to move that many
+statements instead.  Blank lines, comment lines, and continuation lines
+do not count as `statements' for these commands.  So, e.g., you can go
+to the first code statement in a file by entering
+\t\\[beginning-of-buffer]\t to move to the top of the file
+\t\\[py-next-statement]\t to skip over initial comments and blank lines
+Or do `\\[py-previous-statement]' with a huge prefix argument.
+%c:py-previous-statement
+%c:py-next-statement
+%c:py-goto-block-up
+%c:beginning-of-python-def-or-class
+%c:end-of-python-def-or-class
+
+@LITTLE-KNOWN EMACS COMMANDS PARTICULARLY USEFUL IN PYTHON MODE
+
+`\\[indent-new-comment-line]' is handy for entering a multi-line comment.
+
+`\\[set-selective-display]' with a `small' prefix arg is ideally suited for viewing the
+overall class and def structure of a module.
+
+`\\[back-to-indentation]' moves point to a line's first non-blank character.
+
+`\\[indent-relative]' is handy for creating odd indentation.
+
+@OTHER EMACS HINTS
+
+If you don't like the default value of a variable, change its value to
+whatever you do like by putting a `setq' line in your .emacs file.
+E.g., to set the indentation increment to 4, put this line in your
+.emacs:
+\t(setq  py-indent-offset  4)
+To see the value of a variable, do `\\[describe-variable]' and enter the variable
+name at the prompt.
+
+When entering a key sequence like `C-c C-n', it is not necessary to
+release the CONTROL key after doing the `C-c' part -- it suffices to
+press the CONTROL key, press and release `c' (while still holding down
+CONTROL), press and release `n' (while still holding down CONTROL), &
+then release CONTROL.
+
+Entering Python mode calls with no arguments the value of the variable
+`py-mode-hook', if that value exists and is not nil; see the `Hooks'
+section of the Elisp manual for details.
+
+Obscure:  When python-mode is first loaded, it looks for all bindings
+to newline-and-indent in the global keymap, and shadows them with
+local bindings to py-newline-and-indent."))

+Python is an interpreted, interactive, object-oriented programming
+language that combines remarkable power with very clear syntax.
+For an introduction to programming in Python you are referred to the
+Python Tutorial.
+The Python Library Reference documents built-in and standard types,
+constants, functions and modules.
+Finally, the Python Reference Manual describes the syntax and
+semantics of the core language in (perhaps too) much detail.

+Python's basic power can be extended with your own modules written in
+C or C++.
+On some (most?) systems such modules may be dynamically loaded.
+Python is also adaptable as an extension language for existing
+applications.
+See the internal documentation for hints.
+.SH COMMAND LINE OPTIONS
+.TP
+.TP
+.B \-d
+Turn on parser debugging output (for wizards only, depending on
+compilation options).
+.B \-i
+When a script is passed as first argument or the \fB\-c\fP option is
+used, enter interactive mode after executing the script or the
+command.  This can be useful to inspect global variables or a stack
+trace when a script raises an exception.
+.TP
+.B \-i
+When executing a program from a file, this option enters interactive
+mode after the program has completed.  It does not read the
+$PYTHONSTARTUP file.
+.TP
+.B \-k
+This hack, eh, feature is intended to help you to find expression
+statements that print a value.  Although a feature of the language, it
+can sometimes be annoying that when a function is called which returns
+a value that is not
+.IR None ,
+the value is printed to standard output, and it is not always easy to
+find which statement is the cause of an unwanted `1', for instance.
+When this option is set, if an expression statement prints its value,
+the exception
+.I RuntimeError
+is raised.  The resulting stack trace will help you to track down the
+culprit.
+.TP
+.B \-v
+Print a message each time a module is initialized, showing the place
+(filename or built-in module) from which it is loaded.
+.TP
+.BI "\-c " command
+Specify the command to execute (see next section).
+This terminates the option list (following options are passed as
+arguments to the command).
+.PP
+When the interpreter is configured to contain the
+.I stdwin
+built-in module for use with the X window system, additional command
+line options common to most X applications are recognized (by STDWIN),
+e.g.
+.B \-display
+.I displayname
+and
+.B \-geometry
+.I widthxheight+x+y.
+The complete set of options is described in the STDWIN documentation.
+.SH INTERPRETER INTERFACE
+The interpreter interface resembles that of the UNIX shell: when
+called with standard input connected to a tty device, it prompts for
+commands and executes them until an EOF is read; when called with a
+file name argument or with a file as standard input, it reads and
+executes a
+.I script
+from that file;
+when called with
+.B \-c
+.I command,
+it executes the Python statement(s) given as
+.I command.
+Here
+.I command
+may contain multiple statements separated by newlines.
+Leading whitespace is significant in Python statements!
+In non-interactive mode, the entire input is parsed befored it is
+executed.
+.PP
+If available, the script name and additional arguments thereafter are
+passed to the script in the Python variable
+.I sys.argv ,
+which is a list of strings (you must first
+.I import sys
+to be able to access it).
+If no script name is given,
+.I sys.argv
+is empty; if
+.B \-c
+is used,
+.I sys.argv[0]
+contains the string
+.I '-c'.
+Note that options interpreter by the Python interpreter or by STDWIN
+are not placed in
+.I sys.argv.
+.PP
+In interactive mode, the primary prompt is `>>>'; the second prompt
+(which appears when a command is not complete) is `...'.
+The prompts can be changed by assignment to
+.I sys.ps1
+or
+.I sys.ps2.
+The interpreter quits when it reads an EOF at a prompt.
+When an unhandled exception occurs, a stack trace is printed and
+control returns to the primary prompt; in non-interactive mode, the
+interpreter exits after printing the stack trace.
+The interrupt signal raises the
+.I Keyboard\%Interrupt
+exception; other UNIX signals are not caught (except that SIGPIPE is
+sometimes ignored, in favor of the
+.I IOError
+exception).  Error messages are written to stderr.
+.SH FILES AND DIRECTORIES
+These are subject to difference depending on local installation
+conventions:
+.IP /usr/local/bin/python
+Recommended location of the interpreter.
+.IP /usr/local/lib/python
+Recommended location of the directory containing the standard modules.
+.SH ENVIRONMENT VARIABLES
+.IP PYTHONPATH
+Augments the default search path for module files.
+The format is the same as the shell's $PATH: one or more directory
+pathnames separated by colons.
+Non-existant directories are silently ignored.
+The default search path is installation dependent, but always begins
+with `.', (for example,
+.I .:/usr/local/lib/python ).
+The default search path is appended to $PYTHONPATH.
+The search path can be manipulated from within a Python program as the
+variable
+.I sys.path .
+.IP PYTHONSTARTUP
+If this is the name of a readable file, the Python commands in that
+file are executed before the first prompt is displayed in interactive
+mode.
+The file is executed in the same name space where interactive commands
+are executed so that objects defined or imported in it can be used
+without qualification in the interactive session.
+You can also change the prompts
+.I sys.ps1
+and
+.I sys.ps2
+in this file.
+.IP PYTHONDEBUG
+If this is set to a non-empty string it is equivalent to specifying
+the \fB\-d\fP option.
+.IP PYTHONINSPECT
+If this is set to a non-empty string it is equivalent to specifying
+the \fB\-i\fP option.
+.IP PYTHONKILLPRINT
+If this is set to a non-empty string it is equivalent to specifying
+the \fB\-k\fP option.
+.IP PYTHONVERBOSE
+If this is set to a non-empty string it is equivalent to specifying
+the \fB\-v\fP option.

+.SH BUGS AND CAVEATS
+The first time
+.I stdwin
+is imported, it initializes the STDWIN library.
+If this initialization fails, e.g. because the display connection
+fails, the interpreter aborts immediately.
