# svg2png.sh - render SVG file to PNG using inkscape
#
# Usage: svg2png.sh name.svg [inkscape-opts]
#
#    SVG file name.svg will be converted to PNG file name.png in cwd
#
# Note that this requires rsh to mungerabah since for some reason 
# tech services can/will only install inkscape on that particular machine
# (from which the filesystems I am using on this one (charikar) are not
# available). So we have to rcp the input to mungerabah,
# rsh to run it on mungerabah and rcp the output back here.
#
# This requiers appropriate entries in .rhosts on mungerabah for the
# machine this is run from to allow rsh with no passwd.
#
# Note also if run this script on mungerabahu
# (which is also node00.cluster.cs.mu.oz.au)
# then we just run it directly.
