- Removed the subsection numbering in section B (each time a new license is inserted in the front, the others have to be renumbered). - Changed the words in the intro to avoid implying that 1.6.1 is GPL-compatible.

fnmatch.py
"""Filename matching with shell patterns.
fnmatch(FILENAME, PATTERN) matches according to the local convention.
fnmatchcase(FILENAME, PATTERN) always takes case in account.
The functions operate by translating the pattern into a regular
expression. They cache the compiled regular expressions for speed.
The function translate(PATTERN) returns a regular expression
corresponding to PATTERN. (It does not compile it.)

Patterns are Unix shell style:
* matches everything
? matches any single character
[seq] matches any character in seq
[!seq] matches any char not in seq

Both FILENAME and PATTERN are first case-normalized
if the operating system requires it.
