# This perl plug-in prepares a multilayer RGB image for use as a
# transparent gif. To use this prpoerly, you want to have something
# close to the intended background as the bottom layer. If convert
# to indexed is not selected, the bottom two options are unused.
#
# TODO: Write a nicer GUI than Gimp::Fu provides (learn some gtk)
# Anything else that seems useful
