#!/bin/bash
# This is a self-extracting archive that installs Ink/Stitch on your Linux
# system. This first part is an installer, and after that is a .tar.zx file
# containing Ink/Stitch itself.
#
# To install, simply run this script:
#
# sh inkstitch-<version>.sh
#
#
# EXPERT STUFF BELOW:
#
# If you'd rather install it yourself, run this script with --extract to
# produce the original inkstitch-<version>.tar.xz file in the current
# directory.
#
# This script will attempt to determine where to install Inkscape user
# extensions automatically. If it gets it wrong, you can set one of these
# environment variables:
#
# INKSCAPE_PATH (ex: /usr/bin/inkscape)
# The path to the inkscape executable program. This script will ask that program
# where to install extensions by passing it the --user-data-directory argument.
#
# INKSCAPE_EXTENSIONS_PATH (ex: $HOME/.config/inkscape/extensions)
# The path to the inkscape extensions directory. Use this to bypass the
# --user-data-directory method and specify a directory yourself.
