+- ArrayIO uses an array object internally, but all its interfaces

+- Using a real file is often faster (but less convenient).
+- fileno() is left unimplemented so that code which uses it triggers

+- Seeking far beyond EOF and then writing will insert real null

+"""Object-oriented interface to the parser module.
+
+This module exports three classes which together provide an interface
+to the parser module.  Together, the three classes represent two ways
+to create parsed representations of Python source and the two starting
+data types (source text and tuple representations).  Each class
+provides interfaces which are identical other than the constructors.
+The constructors are described in detail in the documentation for each
+class and the remaining, shared portion of the interface is documented
+below.  Briefly, the three classes provided are:
+
+AST
+    Defines the primary interface to the AST objects and supports creation
+    from the tuple representation of the parse tree.
+
+ExpressionAST
+    Supports creation of expression constructs from source text.
+
+SuiteAST
+    Supports creation of statement suites from source text.
+
+FileSuiteAST
+    Convenience subclass of the `SuiteAST' class; loads source text of the
+    suite from an external file.
+
+Aside from the constructors, several methods are provided to allow
+access to the various interpretations of the parse tree and to check
+conditions of the construct represented by the parse tree.
+
+ast()
+    Returns the corresponding `parser.ASTType' object.
+
+code()
+    Returns the compiled code object.
+
+filename()
+    Returns the name of the associated source file, if known.
+
+isExpression()
+    Returns true value if parse tree represents an expression, or a false
+    value otherwise.
+
+isSuite()
+    Returns true value if parse tree represents a suite of statements, or
+    a false value otherwise.
+
+text()
+    Returns the source text, or None if not available.
+
+tuple()
+    Returns the tuple representing the parse tree.

+
+    The following explanation of HTTP serves to guide you through the
+    code as well as to expose any misunderstandings I may have about
+    HTTP (so you don't need to read the code to figure out I'm wrong
+    :-).
+
+    HTTP (HyperText Transfer Protocol) is an extensible protocol on
+    top of a reliable stream transport (e.g. TCP/IP).  The protocol
+    recognizes three parts to a request:
+
+    1. One line identifying the request type and path
+    2. An optional set of RFC-822-style headers
+    3. An optional data part
+
+    The headers and data are separated by a blank line.
+
+    The first line of the request has the form
+
+    <command> <path> <version>
+
+    where <command> is a (case-sensitive) keyword such as GET or POST,
+    <path> is a string containing path information for the request,
+    and <version> should be the string "HTTP/1.0".  <path> is encoded
+    using the URL encoding scheme (using %xx to signify the ASCII
+    character with hex code xx).
+
+    The protocol is vague about whether lines are separated by LF
+    characters or by CRLF pairs -- for compatibility with the widest
+    range of clients, both should be accepted.  Similarly, whitespace
+    in the request line should be treated sensibly (allowing multiple
+    spaces between components and allowing trailing whitespace).
+
+    Similarly, for output, lines ought to be separated by CRLF pairs
+    but most clients grok LF characters just fine.
+
+    If the first line of the request has the form
+
+    <command> <path>
+
+    (i.e. <version> is left out) then this is assumed to be an HTTP
+    0.9 request; this form has no optional headers and data part and
+    the reply consists of just the data.
+
+    The reply form of the HTTP 1.0 protocol again has three parts:
+
+    1. One line giving the response code
+    2. An optional set of RFC-822-style headers
+    3. The data
+
+    Again, the headers and data are separated by a blank line.
+
+    The response code line has the form
+
+    <version> <responsecode> <responsestring>
+
+    where <version> is the protocol version (always "HTTP/1.0"),
+    <responsecode> is a 3-digit response code indicating success or
+    failure of the request, and <responsestring> is an optional
+    human-readable string explaining what the response code means.
+
+    This server parses the request and the headers, and then calls a
+    function specific to the request type (<command>).  Specifically,
+    a request SPAM will be handled by a method handle_SPAM().  If no
+    such method exists the server sends an error response to the
+    client.  If it exists, it is called with no arguments:
+
+    do_SPAM()
+
+    Note that the request name is case sensitive (i.e. SPAM and spam
+    are different requests).
+
+    The various request details are stored in instance variables:
+
+    - client_address is the client IP address in the form (host,
+    port);
+
+    - command, path and version are the broken-down request line;
+
+    - headers is an instance of mimetools.Message (or a derived
+    class) containing the header information;
+
+    - rfile is a file object open for reading positioned at the
+    start of the optional input data part;
+
+    - wfile is a file object open for writing.
+
+    IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING!
+
+    The first thing to be written must be the response line.  Then
+    follow 0 or more header lines, then a blank line, and then the
+    actual data (if any).  The meaning of the header lines depends on
+    the command executed by the server; in most cases, when data is
+    returned, there should be at least one header line of the form
+
+    Content-type: <type>/<subtype>
+
+    where <type> and <subtype> should be registered MIME types,
+    e.g. "text/html" or "text/plain".

+"""Bastionification utility.
+
+A bastion (for another object -- the 'original') is an object that has
+the same methods as the original but does not give access to its
+instance variables.  Bastions have a number of uses, but the most
+obvious one is to provide code executing in restricted mode with a
+safe interface to an object implemented in unrestricted mode.
+
+The bastionification routine has an optional second argument which is
+a filter function.  Only those methods for which the filter method
+(called with the method name as argument) returns true are accessible.
+The default filter method returns true unless the method name begins
+with an underscore.
+
+There are a number of possible implementations of bastions.  We use a
+'lazy' approach where the bastion's __getattr__() discipline does all
+the work for a particular method the first time it is used.  This is
+usually fastest, especially if the user doesn't call all available
+methods.  The retrieved methods are stored as instance variables of
+the bastion, so the overhead is only occurred on the first use of each
+method.

+# Complex numbers
+# ---------------
+
+# This module represents complex numbers as instances of the class Complex.
+# A Complex instance z has two data attribues, z.re (the real part) and z.im
+# (the imaginary part).  In fact, z.re and z.im can have any value -- all
+# arithmetic operators work regardless of the type of z.re and z.im (as long
+# as they support numerical operations).
+#
+# The following functions exist (Complex is actually a class):
+# Complex([re [,im]) -> creates a complex number from a real and an imaginary part
+# IsComplex(z) -> true iff z is a complex number (== has .re and .im attributes)
+# Polar([r [,phi [,fullcircle]]]) ->
+#	the complex number z for which r == z.radius() and phi == z.angle(fullcircle)
+#	(r and phi default to 0)
+#
+# Complex numbers have the following methods:
+# z.abs() -> absolute value of z
+# z.radius() == z.abs()
+# z.angle([fullcircle]) -> angle from positive X axis; fullcircle gives units
+# z.phi([fullcircle]) == z.angle(fullcircle)
+#
+# These standard functions and unary operators accept complex arguments:
+# abs(z)
+# -z
+# +z
+# not z
+# repr(z) == `z`
+# str(z)
+# hash(z) -> a combination of hash(z.re) and hash(z.im) such that if z.im is zero
+#            the result equals hash(z.re)
+# Note that hex(z) and oct(z) are not defined.
+#
+# These conversions accept complex arguments only if their imaginary part is zero:
+# int(z)
+# long(z)
+# float(z)
+#
+# The following operators accept two complex numbers, or one complex number
+# and one real number (int, long or float):
+# z1 + z2
+# z1 - z2
+# z1 * z2
+# z1 / z2
+# pow(z1, z2)
+# cmp(z1, z2)
+# Note that z1 % z2 and divmod(z1, z2) are not defined,
+# nor are shift and mask operations.
+#
+# The standard module math does not support complex numbers.
+# (I suppose it would be easy to implement a cmath module.)
+#

+"""Generic socket server classes.
+
+This module tries to capture the various aspects of defining a server:
+
+- address family:
+	- AF_INET: IP (Internet Protocol) sockets (default)
+	- AF_UNIX: Unix domain sockets
+	- others, e.g. AF_DECNET are conceivable (see <socket.h>
+- socket type:
+	- SOCK_STREAM (reliable stream, e.g. TCP)
+	- SOCK_DGRAM (datagrams, e.g. UDP)
+- client address verification before further looking at the request
+	(This is actually a hook for any processing that needs to look
+	 at the request before anything else, e.g. logging)
+- how to handle multiple requests:
+	- synchronous (one request is handled at a time)
+	- forking (each request is handled by a new process)
+	- threading (each request is handled by a new thread)
+
+The classes in this module favor the server type that is simplest to
+write: a synchronous TCP/IP server.  This is bad class design, but
+save some typing.  (There's also the issue that a deep class hierarchy
+slows down method lookups.)
+
+There are four classes in an inheritance diagram that represent
+synchronous servers of four types:
+
+	+-----------+        +------------------+
+	| TCPServer |------->| UnixStreamServer |
+	+-----------+        +------------------+
+	      |
+	      v
+	+-----------+        +--------------------+
+	| UDPServer |------->| UnixDatagramServer |
+	+-----------+        +--------------------+
+
+(Note that UnixDatagramServer derives from UDPServer, not from
+UnixStreamServer -- the only difference between an IP and a Unix
+stream server is the address family, which is simply repeated in both
+unix server classes.)
+
+Forking and threading versions of each type of server can be created
+using the ForkingServer and ThreadingServer mix-in classes.  For
+instance, a threading UDP server class is created as follows:
+
+	class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass
+
+(The Mix-in class must come first, since it overrides a method defined
+in UDPServer!)
+
+To implement a service, you must derive a class from
+BaseRequestHandler and redefine its handle() method.  You can then run
+various versions of the service by combining one of the server classes
+with your request handler class.
+
+The request handler class must be different for datagram or stream
+services.  This can be hidden by using the mix-in request handler
+classes StreamRequestHandler or DatagramRequestHandler.
+
+Of course, you still have to use your head!
+
+For instance, it makes no sense to use a forking server if the service
+contains state in memory that can be modified by requests (since the
+modifications in the child process would never reach the initial state
+kept in the parent process and passed to each child).  In this case,
+you can use a threading server, but you will probably have to use
+locks to avoid two requests that come in nearly simultaneous to apply
+conflicting changes to the server state.
+
+On the other hand, if you are building e.g. an HTTP server, where all
+data is stored externally (e.g. in the file system), a synchronous
+class will essentially render the service "deaf" while one request is
+being handled -- which may be for a very long time if a client is slow
+to reqd all the data it has requested.  Here a threading or forking
+server is appropriate.
+
+In some cases, it may be appropriate to process part of a request
+synchronously, but to finish processing in a forked child depending on
+the request data.  This can be implemented by using a synchronous
+server and doing an explicit fork in the request handler class's
+handle() method.
+
+Another approach to handling multiple simultaneous requests in an
+environment that supports neither threads nor fork (or where these are
+too expensive or inappropriate for the service) is to maintain an
+explicit table of partially finished requests and to use select() to
+decide which request to work on next (or whether to handle a new
+incoming request).  This is particularly important for stream services
+where each client can potentially be connected for a long time (if
+threads or subprocesses can't be used).
+
+Future work:
+- Standard classes for Sun RPC (which uses either UDP or TCP)
+- Standard mix-in classes to implement various authentication
+  and encryption schemes
+- Standard framework for select-based multiplexing
+
+XXX Open problems:
+- What to do with out-of-band data?

+# This module contains several routines that help recognizing sound
+# files.
+#
+# Function whathdr() recognizes various types of sound file headers.
+# It understands almost all headers that SOX can decode.
+#
+# The return tuple contains the following items, in this order:
+# - file type (as SOX understands it)
+# - sampling rate (0 if unknown or hard to decode)
+# - number of channels (0 if unknown or hard to decode)
+# - number of frames in the file (-1 if unknown or hard to decode)
+# - number of bits/sample, or 'U' for U-LAW, or 'A' for A-LAW
+#
+# If the file doesn't have a recognizable type, it returns None.
+# If the file can't be opened, IOError is raised.
+#
+# To compute the total time, divide the number of frames by the
+# sampling rate (a frame contains a sample for each channel).
+#
+# Function whatraw() calls the "whatsound" program and interprets its
+# output.  You'll have to guess the sampling rate by listening though!
+#
+# Function what() calls whathdr() and if it doesn't recognize the file
+# then calls whatraw().
+#
+# Finally, the function test() is a simple main program that calls
+# what() for all files mentioned on the argument list.  For directory
+# arguments it calls what() for all files in that directory.  Default
+# argument is "." (testing all files in the current directory).  The
+# option -r tells it to recurse down directories found inside
+# explicitly given directories.
+#
+# The file structure is top-down except that the test program and its

+"""Object-oriented interface to the parser module.
+
+This module exports three classes which together provide an interface
+to the parser module.  Together, the three classes represent two ways
+to create parsed representations of Python source and the two starting
+data types (source text and tuple representations).  Each class
+provides interfaces which are identical other than the constructors.
+The constructors are described in detail in the documentation for each
+class and the remaining, shared portion of the interface is documented
+below.  Briefly, the three classes provided are:
+
+AST
+    Defines the primary interface to the AST objects and supports creation
+    from the tuple representation of the parse tree.
+
+ExpressionAST
+    Supports creation of expression constructs from source text.
+
+SuiteAST
+    Supports creation of statement suites from source text.
+
+FileSuiteAST
+    Convenience subclass of the `SuiteAST' class; loads source text of the
+    suite from an external file.
+
+Aside from the constructors, several methods are provided to allow
+access to the various interpretations of the parse tree and to check
+conditions of the construct represented by the parse tree.
+
+ast()
+    Returns the corresponding `parser.ASTType' object.
+
+code()
+    Returns the compiled code object.
+
+filename()
+    Returns the name of the associated source file, if known.
+
+isExpression()
+    Returns true value if parse tree represents an expression, or a false
+    value otherwise.
+
+isSuite()
+    Returns true value if parse tree represents a suite of statements, or
+    a false value otherwise.
+
+text()
+    Returns the source text, or None if not available.
+
+tuple()
+    Returns the tuple representing the parse tree.

+
+    The following explanation of HTTP serves to guide you through the
+    code as well as to expose any misunderstandings I may have about
+    HTTP (so you don't need to read the code to figure out I'm wrong
+    :-).
+
+    HTTP (HyperText Transfer Protocol) is an extensible protocol on
+    top of a reliable stream transport (e.g. TCP/IP).  The protocol
+    recognizes three parts to a request:
+
+    1. One line identifying the request type and path
+    2. An optional set of RFC-822-style headers
+    3. An optional data part
+
+    The headers and data are separated by a blank line.
+
+    The first line of the request has the form
+
+    <command> <path> <version>
+
+    where <command> is a (case-sensitive) keyword such as GET or POST,
+    <path> is a string containing path information for the request,
+    and <version> should be the string "HTTP/1.0".  <path> is encoded
+    using the URL encoding scheme (using %xx to signify the ASCII
+    character with hex code xx).
+
+    The protocol is vague about whether lines are separated by LF
+    characters or by CRLF pairs -- for compatibility with the widest
+    range of clients, both should be accepted.  Similarly, whitespace
+    in the request line should be treated sensibly (allowing multiple
+    spaces between components and allowing trailing whitespace).
+
+    Similarly, for output, lines ought to be separated by CRLF pairs
+    but most clients grok LF characters just fine.
+
+    If the first line of the request has the form
+
+    <command> <path>
+
+    (i.e. <version> is left out) then this is assumed to be an HTTP
+    0.9 request; this form has no optional headers and data part and
+    the reply consists of just the data.
+
+    The reply form of the HTTP 1.0 protocol again has three parts:
+
+    1. One line giving the response code
+    2. An optional set of RFC-822-style headers
+    3. The data
+
+    Again, the headers and data are separated by a blank line.
+
+    The response code line has the form
+
+    <version> <responsecode> <responsestring>
+
+    where <version> is the protocol version (always "HTTP/1.0"),
+    <responsecode> is a 3-digit response code indicating success or
+    failure of the request, and <responsestring> is an optional
+    human-readable string explaining what the response code means.
+
+    This server parses the request and the headers, and then calls a
+    function specific to the request type (<command>).  Specifically,
+    a request SPAM will be handled by a method handle_SPAM().  If no
+    such method exists the server sends an error response to the
+    client.  If it exists, it is called with no arguments:
+
+    do_SPAM()
+
+    Note that the request name is case sensitive (i.e. SPAM and spam
+    are different requests).
+
+    The various request details are stored in instance variables:
+
+    - client_address is the client IP address in the form (host,
+    port);
+
+    - command, path and version are the broken-down request line;
+
+    - headers is an instance of mimetools.Message (or a derived
+    class) containing the header information;
+
+    - rfile is a file object open for reading positioned at the
+    start of the optional input data part;
+
+    - wfile is a file object open for writing.
+
+    IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING!
+
+    The first thing to be written must be the response line.  Then
+    follow 0 or more header lines, then a blank line, and then the
+    actual data (if any).  The meaning of the header lines depends on
+    the command executed by the server; in most cases, when data is
+    returned, there should be at least one header line of the form
+
+    Content-type: <type>/<subtype>
+
+    where <type> and <subtype> should be registered MIME types,
+    e.g. "text/html" or "text/plain".

+"""Bastionification utility.
+
+A bastion (for another object -- the 'original') is an object that has
+the same methods as the original but does not give access to its
+instance variables.  Bastions have a number of uses, but the most
+obvious one is to provide code executing in restricted mode with a
+safe interface to an object implemented in unrestricted mode.
+
+The bastionification routine has an optional second argument which is
+a filter function.  Only those methods for which the filter method
+(called with the method name as argument) returns true are accessible.
+The default filter method returns true unless the method name begins
+with an underscore.
+
+There are a number of possible implementations of bastions.  We use a
+'lazy' approach where the bastion's __getattr__() discipline does all
+the work for a particular method the first time it is used.  This is
+usually fastest, especially if the user doesn't call all available
+methods.  The retrieved methods are stored as instance variables of
+the bastion, so the overhead is only occurred on the first use of each
+method.

+# Complex numbers
+# ---------------
+
+# This module represents complex numbers as instances of the class Complex.
+# A Complex instance z has two data attribues, z.re (the real part) and z.im
+# (the imaginary part).  In fact, z.re and z.im can have any value -- all
+# arithmetic operators work regardless of the type of z.re and z.im (as long
+# as they support numerical operations).
+#
+# The following functions exist (Complex is actually a class):
+# Complex([re [,im]) -> creates a complex number from a real and an imaginary part
+# IsComplex(z) -> true iff z is a complex number (== has .re and .im attributes)
+# Polar([r [,phi [,fullcircle]]]) ->
+#	the complex number z for which r == z.radius() and phi == z.angle(fullcircle)
+#	(r and phi default to 0)
+#
+# Complex numbers have the following methods:
+# z.abs() -> absolute value of z
+# z.radius() == z.abs()
+# z.angle([fullcircle]) -> angle from positive X axis; fullcircle gives units
+# z.phi([fullcircle]) == z.angle(fullcircle)
+#
+# These standard functions and unary operators accept complex arguments:
+# abs(z)
+# -z
+# +z
+# not z
+# repr(z) == `z`
+# str(z)
+# hash(z) -> a combination of hash(z.re) and hash(z.im) such that if z.im is zero
+#            the result equals hash(z.re)
+# Note that hex(z) and oct(z) are not defined.
+#
+# These conversions accept complex arguments only if their imaginary part is zero:
+# int(z)
+# long(z)
+# float(z)

+"""Generic socket server classes.
+
+This module tries to capture the various aspects of defining a server:
+
+- address family:
+	- AF_INET: IP (Internet Protocol) sockets (default)
+	- AF_UNIX: Unix domain sockets
+	- others, e.g. AF_DECNET are conceivable (see <socket.h>
+- socket type:
+	- SOCK_STREAM (reliable stream, e.g. TCP)
+	- SOCK_DGRAM (datagrams, e.g. UDP)
+- client address verification before further looking at the request
+	(This is actually a hook for any processing that needs to look
+	 at the request before anything else, e.g. logging)
+- how to handle multiple requests:
+	- synchronous (one request is handled at a time)
+	- forking (each request is handled by a new process)
+	- threading (each request is handled by a new thread)
+
+The classes in this module favor the server type that is simplest to
+write: a synchronous TCP/IP server.  This is bad class design, but
+save some typing.  (There's also the issue that a deep class hierarchy
+slows down method lookups.)
+
+There are four classes in an inheritance diagram that represent
+synchronous servers of four types:
+
+	+-----------+        +------------------+
+	| TCPServer |------->| UnixStreamServer |
+	+-----------+        +------------------+
+	      |
+	      v
+	+-----------+        +--------------------+
+	| UDPServer |------->| UnixDatagramServer |
+	+-----------+        +--------------------+
+
+(Note that UnixDatagramServer derives from UDPServer, not from
+UnixStreamServer -- the only difference between an IP and a Unix
+stream server is the address family, which is simply repeated in both
+unix server classes.)
+
+Forking and threading versions of each type of server can be created
+using the ForkingServer and ThreadingServer mix-in classes.  For
+instance, a threading UDP server class is created as follows:
+
+	class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass
+
+(The Mix-in class must come first, since it overrides a method defined
+in UDPServer!)
+
+To implement a service, you must derive a class from
+BaseRequestHandler and redefine its handle() method.  You can then run
+various versions of the service by combining one of the server classes
+with your request handler class.
+
+The request handler class must be different for datagram or stream
+services.  This can be hidden by using the mix-in request handler
+classes StreamRequestHandler or DatagramRequestHandler.
+
+Of course, you still have to use your head!
+
+For instance, it makes no sense to use a forking server if the service
+contains state in memory that can be modified by requests (since the
+modifications in the child process would never reach the initial state
+kept in the parent process and passed to each child).  In this case,
+you can use a threading server, but you will probably have to use
+locks to avoid two requests that come in nearly simultaneous to apply
+conflicting changes to the server state.
+
+On the other hand, if you are building e.g. an HTTP server, where all
+data is stored externally (e.g. in the file system), a synchronous
+class will essentially render the service "deaf" while one request is
+being handled -- which may be for a very long time if a client is slow
+to reqd all the data it has requested.  Here a threading or forking
+server is appropriate.
+
+In some cases, it may be appropriate to process part of a request
+synchronously, but to finish processing in a forked child depending on
+the request data.  This can be implemented by using a synchronous
+server and doing an explicit fork in the request handler class's
+handle() method.
+
+Another approach to handling multiple simultaneous requests in an
+environment that supports neither threads nor fork (or where these are
+too expensive or inappropriate for the service) is to maintain an
+explicit table of partially finished requests and to use select() to
+decide which request to work on next (or whether to handle a new
+incoming request).  This is particularly important for stream services
+where each client can potentially be connected for a long time (if
+threads or subprocesses can't be used).
+
+Future work:
+- Standard classes for Sun RPC (which uses either UDP or TCP)
+- Standard mix-in classes to implement various authentication
+  and encryption schemes
+- Standard framework for select-based multiplexing
+
+XXX Open problems:
+- What to do with out-of-band data?

+# This module contains several routines that help recognizing sound
+# files.
+#
+# Function whathdr() recognizes various types of sound file headers.
+# It understands almost all headers that SOX can decode.
+#
+# The return tuple contains the following items, in this order:
+# - file type (as SOX understands it)
+# - sampling rate (0 if unknown or hard to decode)
+# - number of channels (0 if unknown or hard to decode)
+# - number of frames in the file (-1 if unknown or hard to decode)
+# - number of bits/sample, or 'U' for U-LAW, or 'A' for A-LAW
+#
+# If the file doesn't have a recognizable type, it returns None.
+# If the file can't be opened, IOError is raised.
+#
+# To compute the total time, divide the number of frames by the
+# sampling rate (a frame contains a sample for each channel).
+#
+# Function whatraw() calls the "whatsound" program and interprets its
+# output.  You'll have to guess the sampling rate by listening though!
+#
+# Function what() calls whathdr() and if it doesn't recognize the file
+# then calls whatraw().
+#
+# Finally, the function test() is a simple main program that calls
+# what() for all files mentioned on the argument list.  For directory
+# arguments it calls what() for all files in that directory.  Default
+# argument is "." (testing all files in the current directory).  The
+# option -r tells it to recurse down directories found inside
+# explicitly given directories.
+#
+# The file structure is top-down except that the test program and its
