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

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

   latex source2e.tex

   makeindex -s source2e.ist source2e.idx
   makeindex -s gglo.ist -o source2e.gls source2e.glo

   latex source2e.tex
   latex source2e.tex


The makeindex style source2e.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 batch file automates this.
  (It could easily be ported to scripts for DOS or VMS,
   rm is ReMove a file, and echo "..." > file writes ... to "file".)

On a sparc10 sun unix machine, this script takes
about 17 minutes to run.


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

rm  source2e.gls source2e.ind source2e.toc

echo "" > ltxdoc.cfg

makeindex -s source2e.ist source2e.idx
makeindex -s gglo.ist -o source2e.gls source2e.glo

echo "\includeonly{}" > ltxdoc.cfg
