README

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The Python Reference Manual is no longer maintained in LaTeX.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 our site,
we 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 if I find a bug?
---------------------

First, check that the bug is present in the online version of the
documentation at <http://www.python.org/docs/>; we may have already
fixed it.

If we haven't, tell us about it.  We'd like the documentation to be
complete and accurate, but have limited time.  If you discover any
inconsistencies between the documentation and implementation, or just
have suggestions as to how to improve the documentation, let is know!
Send comments and patches to the Python Documentation Team:

			   python-docs@python.org

Thanks!


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.  Note that the 0.9
release is still in testing; this documentation release was tested
with the 18 Mar 1998 release.  We'll be upgrading to the final version 
when it becomes available.

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 0.12f at the time of this writing).  Versions even
	  a couple of patchlevels different are highly likely to
	  fail due to syntax changes for some of the pdftex
	  primitives.

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.  Find the software at
	  <http://language.perl.com/info/software.html>.

	- 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
texiinputs/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.


What if I want to use A4 paper?
-------------------------------

Edit the file texinputs/manual.cls.  Change the line that reads:

    \LoadClass[twoside,openright]{report}

to say:

    \LoadClass[a4paper,twoside,openright]{report}

Now do a "make clean all" to generate PostScript files.


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, we use Harlequin's webmaker.  We're not very 
happy with it and hope that eventually FrameMaker will be able to
produce HTML without third party help.


What else is in here?
---------------------

There is a new LaTeX document class called "howto".  This is used for
the new series of Python HOWTO documents which is being coordinated by 
Andrew Kuchling <amk@acm.org>.  The file howto.tex is a commented
template which may be used an example.  A script to "do the right
thing" to format a howto document is included as tools/mkhowto.sh.
Support for this document class is still new, but is expected to
evolve rapidly.  Use "mkhowto.sh --help" for information on using the
formatting tool.
