# Inkscape packaging script for Mac OS X
#
# The script creates a read-write disk image, 
# copies Inkscape in it, customizes its appearance using a 
# previously created .DS_Store file (inkscape.ds_store),
# and then compresses the disk image for distribution.

#
# How to update the disk image layout:
# ------------------------------------
#
# Modify the 'dmg_background.svg' file and generate a new 
# 'dmg_background.png' file.
#
# Update the AppleScript file 'dmg_set_style.scpt'.
#
# Run this script with the '-s' option.  It will apply the
# 'dmg_set_style.scpt' AppleScript file, and then prompt the
# user to check the window size # and position before writing
# a new 'inkscape.ds_store' file to work around a bug in Finder
# and AppleScript.  The updated 'inkscape.ds_store' will need 
# to be commited to the repository when this is done.
