Update of /cvsroot/python/python/dist/src/Demo/scripts
In directory sc8-pr-cvs1:/tmp/cvs-serv27228/Demo/scripts

Modified Files:
      Tag: ast-branch
	pp.py README 
Added Files:
      Tag: ast-branch
	find-uname.py 
Log Message:
Merge head to this branch.

Merge all sorts of changes from just before 2.3b1 into the ast
branch.  This should make the eventual merge back to the trunk easier.

The merge is almost entirely porting changes into the ast-branch.
There was no attempt to get changes to compile.c into newcompile.c.
That work should be done when newcompile.c is closer to completion.

The only significant conflicts appeared to be in pythonrun.c.


--- NEW FILE: find-uname.py ---
#!/usr/bin/env python

"""
For each argument on the command line, look for it in the set of all Unicode
names.  Arguments are treated as case-insensitive regular expressions, e.g.:

    % find-uname 'small letter a$' 'horizontal line'
    *** small letter a$ matches ***
    LATIN SMALL LETTER A (97)
    COMBINING LATIN SMALL LETTER A (867)
    CYRILLIC SMALL LETTER A (1072)
    PARENTHESIZED LATIN SMALL LETTER A (9372)
    CIRCLED LATIN SMALL LETTER A (9424)
    FULLWIDTH LATIN SMALL LETTER A (65345)
    *** horizontal line matches ***
    HORIZONTAL LINE EXTENSION (9135)
