# The Python Imaging Library.

# $Id$

#

# a utility to identify image files

#

# this script identifies image files, extracting size and

# pixel mode information for known file formats.  Note that

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

#

# History:

# 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

#
