#                    with code from Sven Hartge <hartge@ds9.argh.org>
#     13 Dec 2000: version 0.0.7 by Samuel Hocevar <sam@zoy.org>

#                    better command line option parsing
#                    able to resize final photos (default 640x480)
#      5 May 2005: version 0.1.0 by Chris Ness <chris@nesser.org>
#                    handles videos and makes a jump link to them (avi,mpg)

#                    no longer prints help message with normal use
#      8 May 2005: version 0.1.1 by Chris ness <chris@nesser.org>
#                    new dependency on `wc` (word count) for videos
#                    I didn't know bash wouldn't let you set a var that is
#                    outside a while loop when you are inside it.  Weird!
