Fixed a bug in the gauss() function. The bug was reported by Mike
Miller, who complained that its kurtosis was bad, and then fixed by
Lambert Meertens (author of the original algorithm) who discovered
that the mathematical analysis leading to his solution was wrong, and
provided a corrected version. Mike then tested the fix and reported
that the kurtosis was now good.

Jeff Kunce writes (and he is right):
Also, I just ran across a [possible] minor glitch
in the library documentation for site.py. It says:
"For example, suppose sys.prefix and
sys.exec_prefix are set to `/usr/local'. The
Python 1.5 library is then installed in
`/usr/local/lib/python1.5'. Suppose this has a
subdirectory `/usr/local/python1.5/site-packages'
with three subsubdirectories, `foo', `bar' and
`spam'..."
I think it should be:
"...Suppose this has a subdirectory
`/usr/local/lib/python1.5/site-packages' with..."

Fix some outdated comments (mostly by removing a large comment block
that was only causing confusing). Add free(userpath) and
free(machinepath) statements to prevent some leaks.

Moved clear_carefully() to _PyModule_Clear() in moduleobject.c
(modified) and use that.
Some differences in the cleanup algorithm:
- Clear __main__ before the other modules.
- Delete more sys variables: including ps1, ps2, exitfunc, argv, and
even path -- this will prevent new imports!
- Restore stdin, stdout, stderr from __stdin__, __stdout__,
__stderr__, effectively deleting hooks that the user might have
installed -- so their (the hooks') destructors will run.

Add internal routine _PyModule_Clear(), which does approximately what
clear_carefully() used to do in import.c. Differences: leave only
__builtins__ alone in the 2nd pass; and don't clear the dictionary (on
the theory that as long as there are references left to the
dictionary, those might be destructors that might expect __builtins__
to be alive when they run; and __builtins__ can't normally be part of
a cycle).

&do_cmd_url,
&do_cmd_email: Adjust to use a font similar to that used in the printed

&my_module_index_helper: Change to be only used for defining markup. Don't
prepend an <A NAME=...> to the result; use the containing page as
the module target for the index.
&ref_module_index_helper: New function. Used only for references to modules
described elsewhere. Generate the right target.
&init_myformat: Set the anchor_mark to an empty string; this avoids junky

Added libsymbol.tex, libtoken.tex to dependencies for the libref.

l2hlib: Added commands to translate node*.html to use the \label{} stuff,

(1) Change normpath() to *not* also call normcase().

turns out that the table constructed for translate() didn't work in

letters.

Several optimizations:
self.__chips now contains the list of rgbtuple values for the
chips named i - 1 (Tkinter counts from 1, we count from zero).
The chip number was just the index + 1. This means color lookup
need not do an itemcget(), it can just index into __chips.
instead of calling __canvas.itemconfigure(), we glom up a huge Tcl
script and call tk.eval() directly. Actually we do many appends
to a Python list, then string.join() them together into one huge
string. This reduces the overhead of Tkinter but making one fast
call to Tcl.

Cache conversions from triplets to rrggbb's and vice versa. Wasteful

Added all-formats target: use this to get both PDF and PS files; using the
"alternate" rules for PDF generation doesn't ensure the PS files get
generated since distiller isn't used.
Switch to the "alternate" rules for PDF generation; this is starting to make
more sense than the distiller-based rule, and requires only free software.
I'm also confident it's working well (meaning I paged through all four
pdflatex-generated PDF files).

Massive changes. Fewer warnings from the Python Library Reference. Still
messy, but the thing seems to be working without bombing completely today.
Formatting lib.texi with TeX doesn't seem to do too badly, either!
Info formatting isn't quite there; that might just have to disappear this
time.

Move optional package inclusions to the top, to make them easier to find.
Code elsewhere in this file tests for the inclusion of the package and does
not need to be uncommented. Comments explain what they do and how to
disable them.
Added support for the optional "fancyhdr" package. If used, page footers
include chapter information on the left and section information on the right.
Both optional packages, "fancyhdr" and "times", are enabled by default. We
may want to disable them before shipping, but I'm not completely convinced.
(How many installations format their own documentation?)
