#
# 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
#
