# screenshot -- a ridiculously simple frontend to xwd, best suited for
#               calling from your window manager.
#
#               for example, i used WPrefs to make WindowMaker take a 
#               full screen shot on PrintScreen and allow me to select
#               a window for a single screen shot (screenshot -i ) on 
#               Shift+PrintScreen.  does anybody know how to get the
#               current window ID out of windowmaker?
#
#               if you don't like subsequent processing with gimp or xv
#               or [your favorite gfx app] then add in a call to convert
#               or something.
