# Implemented support for multiple diverse versions of Inkstitch extensions in Inkscape.
#   - useful for testing and development
#   - useful for comparing different versions of Inkstitch


# this script generates inx files in inx/ directory from xml templates in templates/ directory
# - added support for alternative id registration and menu names for Inkscape extensions
#   - each xml template should be modified to use the new id_inkstitch and menu_inkstitch:
#        <id>org.inkstitch.....</id>    ---> <id>org.{{ id_inkstitch }}.....</id>
#        <submenu name="Ink/Stitch"     ---> <submenu name="{{ menu_inkstitch }}"
#     or input/output xml template should be modified to use the filetypename:
#        <filetypename>Ink/Stitch:...   ---> <filetypename>{{ menu_inkstitch }}:...


# Here's an example of how to use two Inkstitch extensions:
#   - install Inkstitch in two different locations (e.g. inkstitch and inkstitch-k)
#       - check out the Inkstitch repository in two different locations
#   - ensure 'make inx' is executed in both locations
#       - this will generate also inx/locale/ files
#   - generate modified inx files for second location
#       - in the second location:
#            > generate-inx-files -a k
#   - install the inx files in Inkscape extensions directory
#       - symlink .config/inkscape/extensions/inkstitch   -> inkstitch
#       - symlink .config/inkscape/extensions/inkstitch-k -> inkstitch-k
#   - modify .config/inkscape/keys/default.xml if necessary
#   - run Inkscape with both Inkstitch extensions enabled
#       - first version:  Extensions > Ink/Stitch
#       - second version: Extensions > Ink/Stitch-k
