Inkscape - macOs - Absolute Path Wrapper
========================================

On *macOs*, *Inkscape* requires absolute paths to work::

    https://answers.launchpad.net/inkscape/+question/280575

This *Python* module is a wrapper changing the paths given at the command-line
to *Inkscape* for their absolute variant. It should be put in the *$PATH* as
*inkscape* and made executable.
