% \division{Some Typesetting Remarks}
%
% This driver typesets The Source $2_\varepsilon$ included in the 
% \TeX Live 2005 distribution. Some tricks here are done just for
% fixing typos in the Source Files. The Source Files themselves are
% intact.
%
% Most probably you should redefine the |\BasePath| macro so that it
% was the path of the \file{\dots/source/latex/base} directory on your
% system. The path levels should be separated with slashes (even on
% Windows) and should also end with a~slash (to concatenate well with
% the file name).
%
% \stanza
% While \TeX ing The Source again after a~fatally erroneous pass there
% happened the `\TeX\ capacity exceded error' sometimes. \TeX ing once
% again was the right thing to do.
%
% The \pk{hyperref} package usually issues some warnings about non
% existence of some hypertargets. I~consider it rather a~feature of
% \pk{hyperref} (a~bug?) than a~bug in the typeset file(s).
%
% \stanza
% One more thing you shouldn't bother of is the differences of the
% checksums, I~mean the usual \pk{gmdoc} message that the checksum
% stated in the file differs from \pk{gmdoc}'s own count. That is
% O.K.\ since the checksum stated in a~traditional \file{.dtx}
% is the number of backslashes in the macrocodes while the checksum
% handled and expected by \pk{gmdoc} is the number of \emph{the escape ^^B
% chars}. Don't get the difference? Assume the declared code escape
% char is |\| (as usual) and consider |\\| in the code. Due to
% the traditional counting this CS increases the checksum by 2 while
% due to mine by 1: the second bslash is \emph{not} escape char: it's
% the CS name.
%
% Moreover, when you declare |\CodeEscapeChar\!| e.g., the code 
%\[\hbox{|!Alice !\!has !an !aligator|}\]
% increases the `new way' checksum by 5 not by 1 as it would do the
% traditional one.
%
% \stanza
% This driver uses an unofficial little package \pk{gmeometric} to
% allow the |\geometry| command also inside \env{document}. This
% package is included in the drivers' directory.
%

% \division{The Body}
%
% ``This document will typeset the \LaTeX\ sources as a single document.
% This will produce quite a large file (roughly 555 pages) and may
% take a long time.

% of this document's source file, after |\end{document}| (not typeset).''

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

To use this file to produce a fully indexed source code
you need to execute the following (or equivalent) commands:

   latex source2e_by_gmdoc.tex

   makeindex -s gmsource2e.ist source2e_by_gmdoc.idx
   makeindex -s gmglo.ist -o source2e_by_gmdoc.gls source2e_by_gmdoc.glo

   latex source2e_by_gmdoc.tex
   latex source2e_by_gmdoc.tex


The makeindex style gmsource2e.ist is used in place of the usual
doc gind.ist to ensure that I is used in the sequence I J K
not I II II, which would be the default makeindex behaviour.

The third run with latex is only required to get the table of
contents entries for the change log and index. You may speed things up
by using the \includeonly mechanism so as not to typeset the source
files on the second run. This involves changing the file
ltxdoc.cfg
between the latex runs.

The following unix script automates this.
  (It could easily be ported to scripts for DOS or VMS,
   rm is ReMove a file, and echo "..." > file writes ... to "file".)


After this script (after the second ==============) is a similar script
that will produce the documentation for all the files in the base
distribution that are *not* included in source2e.dvi. This second script
was requested, but before using it, beware it will take a long time!
It may however be modified as required, eg to not typeset the fdd files
or whatever...


!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Natror (GM): I~didn't touch the following so it's probably not quite suitable
for gmdoc-ing.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


==============
#!/bin/sh

rm  -f source2e_by_gmdoc.gls source2e_by_gmdoc.ind source2e_by_gmdoc.toc

# First run: 
# Create new standard ltxdoc.cfg file
# Pass the (possibly empty) list of arguments supplied on the
# command line to article class.
#
# If you use A4 paper, running this script with argument
#    a4paper
# may save about 30 pages.
#
echo "\PassOptionsToClass{$*}{article}" > ltxdoc.cfg


# Now LaTeX the file with this cfg file.
#
latex source2e.tex


# Make the Change log and Glossary.
#
makeindex -s source2e.ist source2e.idx
makeindex -s gglo.ist -o source2e.gls source2e.glo


# Second run: append \includeonly{} to ltxdoc.cfg to speed up things
# (this run needed only to get changes and index listed in .toc file)
#
# Note that the index will not be made incorrect by the insertion
# of the table of contents as the front matter uses a diferent page
# numbering scheme.
#
echo "\includeonly{}" >> ltxdoc.cfg

latex source2e.tex


# Third and final run, to put everything together.
# First restore the cfg file:
#
echo "\PassOptionsToClass{$*}{article}" > ltxdoc.cfg
latex source2e.tex


==============
#!/bin/sh

# Running this script will process all the dtx fdd and *guide.tex
# and ltnews*.tex files in the LaTeX distribution, except the dtx
# files included in source2e.tex. 
# (The shell first script in the comments of source2e.tex will
#  process those.)

# Any command line arguments (eg a4paper) are taken as options to the
# article class.

# This script is likely to take ages!

echo "\PassOptionsToClass{$*}{article}"                  > ltxdoc.cfg
echo "\batchmode"                                       >> ltxdoc.cfg

# The next four lines produce full indexes and change logs
# you may not want those.
echo "\AtBeginDocument{\RecordChanges}"                 >> ltxdoc.cfg
echo "\AtEndDocument{\PrintChanges}"                    >> ltxdoc.cfg
echo "\AtBeginDocument{\CodelineIndex\EnableCrossrefs}" >> ltxdoc.cfg
echo "\AtEndDocument{\PrintIndex}"                      >> ltxdoc.cfg

# If you do not want any code listings, just documentation, then instead
# of the above four lines, uncomment the following:
# echo "\AtBeginDocument{\OnlyDescription}"                >> ltxdoc.cfg

echo "\PassOptionsToClass{$*}{article}"                  > ltxguide.cfg
