Clean up index reference to SGMLParser class.

Lots of nits in both.

things in the index.

	macro.  Intended usage:

		\withsubitem{(in module foo)}{\ttindex{myfunc()}}

	This allows indexing functions from other modules/class/whatnot
	without being dependent on the exact expansions of several macros
	internal to python.sty.  It's also easier to read in the source!

Some new "logical" macros that seem to be useful:

\regexp{}:  For regular expressions.  To make it easier to keep the appearance
	consistent.

\mimetype{}:  Don't use \code{}!

\envvar{}:  Environment variable.  This does some indexing as well.

\character{}:  Just a character we want to talk about in the text, but not
	a Python constant.

Improve some index entries.

Markup consistency.

Removed incorrect \setindexsubitem{}.

Add section on using A4 paper, since that's a common request.

Add a -q option for "quiet" operation.  Nothing gets out (not even stderr,
since that's tossed to stdout for capture in the .how file).  It's a good
idea to use -l to get the log in case there are problems.  Maybe this should
be the default and add a --verbose option to get the stdout?  There's way
too much junk output.

a "set -x".

Allow keeping a transcript, using -l, in $FILE.how.

Allow keeping of all the temp files created by the process, using -k.

Leave find_my_file() around for now, even though we're not using it at the
moment.

Python Reference Manual.

Changed example to use "import posixfile" instead of "from posixfile import *"
since only one symbol was used.

Made references to constants in other TERMIOS module explicit in termios
description.

Removed superfluous backslash from example.

Added information on the exception attributes when exceptions are classes.

Kerberos from Python" HOWTO (this will change shortly, I hope).

This needs to be run from it's location in the Doc/tools directory, and
not via a symlink.  I'll try and fix this in the future.

The help message needs work.

.perl file search path, rather than making assumptions about the current
directory.

	underscores.  Might this be a fundamental PDF limitation?  Hm, could
	still be a TeX thing.

	- the .cvsignore files; these are only useful in the CVS tree

	- ref/ref.pdf

	- ref/ref.ps

After compression, these last two account for about one-half MB, and half
the tarball.  They can be picked up from the appropriate format dist if
needed.

Correct misuse of indexsubutem.

Describe the Queue class using {classdesc}{Queue}, not {funcdesc}{__init__}.

Convert one bulleted list to a {tableii} environment; the other should
probably be converted, but I haven't decided to what.
