# Convert files from one format into another.
#
# The GNUmed client expects to be able to run this command
# in a systemwide way, ie. it needs to be accessible in the
# executable $PATH (such that "which gm-convert_file" gives a
# useful answer). There can be several copies per system in
# which way users can override a system default script with
# their own.
#
# Typical locations for this script would be
#
#	/usr/bin/
#	/usr/local/bin/
#	~/bin/
#
# This is just an example. You must install ImageMagick
# to actually use it.
