Python main documentation -- in LaTeX
-------------------------------------

This directory contains the LaTeX sources to the Python documentation
and a published article about Python.

If you don't have LaTeX, you can ftp a tar file containing PostScript
of the 4 main documents.  It should be in the same place where you
fetched the main Python distribution, in a file named
"pythondoc-ps<version>.tar.gz".  (See "../Misc/FAQ" for more
information about ftp-ing Python files.)

The following are the LaTeX source files:

	tut.tex				The tutorial
	lib.tex, lib*.tex		The library reference
	ref.tex, ref[1-8].tex		The reference manual
	ext.tex				How to extend Python
	qua.tex, quabib.bib		Article published in CWI Quarterly

All except qua.tex (which isn't built by the default target) use the
style option file "myformat.sty".  This contains some macro
definitions and sets some style parameters.

The style parameters are set up for European paper size (21 x 29.7 cm,
a.k.a. A4, or roughly 8.27 x 11.7 inch) by default.  To use US paper,
comment out the line saying \input{a4wide.sty} in myformat.sty (you
may want to fiddle with lay-out parameters like \textwidth and
\textheight, since the default format uses rather wide margins).

You need the makeindex utility to produce the index for ref.tex
lib.tex; you need bibtex to produce the references list for qua.tex.

There's a Makefile to call LaTeX and the other utilities in the right
order and the right number of times.  This will produce DVI files for
each document made; to preview them, use xdvi.  PostScript is produced
by the same Makefile target that produces the DVI files.  This uses
the dvips tool.  Printing depends on local conventions; at my site, I
use lpr.  For example:

	make ref			# creates ref.dvi and ref.ps
	xdvi ref			# preview it ref.dvi
	lpr -Ppsc ref.ps		# print it on printer "psc".


Making HTML files
-----------------

The Reference, Tutorial and Extensions manual can all be converted to
HTML using Nikos Drakos' LaTeX2HTML converter.  See the Makefile;
after some twiddling, "make l2h" should do the trick.

The Library manual doesn't work well with LaTeX2HTML; instead, there's
a Python script texi2html.py in this directory that can be run on the
texinfo generated as an intermediate step for generating the INFO
files as described in the next section.  The command "make libwww"
should do this.


Making the INFO version of the Library Reference
------------------------------------------------

The Library Reference can also be read in hypertext form using the
Emacs INFO system.  This uses Texinfo format as an intermediate step.
It requires texinfo version 2 (we have used 2.14).

To build the info files (python-lib.info*), say "make lib.info".  This
takes a while, even on a machine with a 100 MHz clock and 64 Mbytes of
RAM :-).  Please ignore the output, which appears like error messages
but really is debugging output only.

You may have to change a site dependency in fix.el: if texinfo 2.xx
isn't installed by default at your site, you'll have to install it
(use archie to locate a version and ftp to fetch it).  If you can't
install it in the standard Emacs load path, uncomment the line
containing a "(setq load-path ...)" statement, and fill in the path
where you put it.

The files used by the conversion process are:

partparse.py            Python script that converts LaTeX sources to
			texi files.

texi{pre,post}.dat      Files placed before and after the result.

fix.el                  Elisp file executed by Emacs. Two calls to
                        'texinfo-all-menus-update are necessary in
			some cases.

fix_hack		Shell script to fix the results of the
                        "underscore hack". {\ptt \char'137} is
                        back-translated to a simple underscore.  This
                        is needed for the texindex program.

whichlibs		Shell script to print a list of lib*.tex files
			to be processed.

A Million thanks for Jan-Hein B\"uhrman for writing and debugging the
convertor and related scripts, and for fixing the LaTeX sources and
writing new macros for myformat.sty!
