# This script converts the various icons from their SVG
# source format to PNG (for Unix), ICO (for Windows)
# and ICNS (for Mac). It uses the following tools:
#
# rsvg from http://librsvg.sourceforge.net/
# png2icns from http://icns.sourceforge.net/
# icoutil from http://www.nongnu.org/icoutils/
#
# On Fedora, these are available out of the box in the
# packages "librsvg2", "icoutils" and "libicns-utils".
