# This program captures a window (optionally, the entire screen) to a ppm file.
# It then opens the ppm file in the Gimp so that it can be cropped if
# necessary.  The ppm file is then compressed and saved.

# Hint: to capture WAVE's exit confirmation box, run WAVE with the -Wfsdb
# option (see xview(7)) to disable the full-screen grab.
