This is, I guess, a few things the Python devs were just fed up with.
* "while 1" is now "while True"
* Types are compared with isinstance instead of ==
* Sort a list in one go with sorted()
My own twist is to also replace type('') with str, type(()) with tuple,
type([]) with list, type(1) with int, and type(5000.0) with float.

# this script identifies image files, extracting size and

# you don't need the PIL C extension to use this module.

# 0.0 1995-09-01 fl Created
|
|
# 0.1 1996-05-18 fl Modified options, added debugging mode
|
|
# 0.2 1996-12-29 fl Added verify mode
|
|
# 0.3 1999-06-05 fl Don't mess up on class exceptions (1.5.2 and later)
|
|
# 0.4 2003-09-30 fl Expand wildcards on Windows; robustness tweaks
