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

This directory contains the LaTeX sources to the Python documentation.
They now require LaTeX2e (LaTeX 2.09 compatibility is dropped).

The Python Reference Manual is no longer maintained in LaTeX.  It is
now a FrameMaker document.  The FrameMaker 5.0 files (ref.book,
ref*.doc) as well as PostScript generated (ref.ps) from it are in the
subdirectory ref/.  (See ftp://ftp.adobe.com/pub/adobe/framereader for
a free reader for FrameMaker documents, for some platforms.)  Many
thanks to Robin Friedrich for the conversion of the Reference Manual
to FrameMaker and his work on its index.

If you don't have LaTeX, or if you'd rather not format the
documentation yourself, you can ftp a tar file containing HTML, PDF,
or PostScript versions of all documents.  Additional formats may be
available.  These should be in the same place where you fetched the
main Python distribution (try http://www.python.org or
ftp://ftp.python.org).

The following are the LaTeX source files:

	tut.tex				The tutorial
	lib.tex, lib*.tex		The library reference
	ext.tex				How to extend Python
	api.tex				Reference for the Python/C API

All use the "manual" document class and "python" package, derived from 
the old "myformat.sty" style file.  These contains many macro
definitions useful in documenting Python, and set some style parameters.

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 lib			# create lib.dvi and lib.ps
	xdvi lib			# preview lib.dvi
	lpr lib.ps			# print on default printer


What tools do I need?
---------------------

You need to install Python; some of the scripts used to produce the
documentation are written in Python.

The simplest way to get the rest of the tools in the configuration we
used is to install the teTeX TeX distribution, version 0.9.  More
information is available on teTeX at http://www.tug.org/tetex/.  This
is a UNIX-only TeX distribution at this time.

If you don't want to get teTeX, or if you're not using UNIX, here is
what you'll need:

To create DVI, PDF, or PostScript files:

	- LaTeX2e, 1995/12/01 or newer.  Older versions are likely to 
	  choke.

	- makeindex.  This is used to produce the indexes for the
	  library reference and Python/C API reference.

To create PDF files:

	- pdflatex.  We used the one in the teTeX 0.9 distribution
	  (version 0.11 at the time of this writing).

To create PostScript files:

	- dvips.  Most TeX installations include this.  If you don't
	  have one, check CTAN (ftp://ctan.tug.org/tex-archive/).

To create info files:

	- makeinfo.  This is available from any GNU mirror.

To create HTML files:

	- Perl 5.004_04 or newer.  Try www.perl.org for pointers.

	- LaTeX2HTML 98.1p1, or newer.  Releases are available at
	  http://www-dsed.llnl.gov/files/programs/unix/latex2html/.


What if Times fonts are not available?
--------------------------------------

As distributed, the LaTeX documents use PostScript Times fonts.  This
is done since they are much better looking and produce smaller
PostScript files.  If, however, your TeX installation does not support 
them, they may be easily disabled.  Edit the file manual.cls and
comment out the line that starts "\RequirePackage{times}" using a "%"
character at the beginning of the line.  An alternative is to install
the right fonts and LaTeX style file.


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

The LaTeX documents can be converted to HTML using Nikos Drakos'
LaTeX2HTML converter.  See the Makefile; after some twiddling, "make
l2h" should do the trick.

For the reference manual, I use Harlequin's webmaker.  I'm not very
happy with it and hope that eventually FrameMaker will be able to
produce HTML without third party help.
