# FIXME: Inkscape needs better relocation support for OS X (get rid of the relative 
# path hack in src/path-prefix.h for osxapp-enabled builds). Until then, below change
# of working directory is required:
#
# Due to changes after 0.48, we have to change working directory in the script named 'inkscape':
# recursive calls to inkscape from python-based extensions otherwise cause the app to hang or
# fail (for python-based extensions, inkscape changes the working directory to the 
# script's directory, and inkscape launched by python script thus can't find resources
# like the now essential 'units.xml' in INKSCAPE_UIDIR relative to the working directory).
