#
# Build file for creating DMG files.
#
# The DMG packager looks for a template.dmg.bz2 for using as its 
# DMG template. If it doesn't find one, it generates a clean one.
#
# If you create a DMG template, you should make one containing all
# the files listed in $(SOURCE_FILES) below, and arrange everything to suit
# your style. The contents of the files themselves does not matter, so
# they can be empty (they will be overwritten later).
