		Usage: init-build-sys.sh [options] [version_switch] ADDON_DIRECTORY OUTPUT_DIRECTORY

		init-build-sys.sh generates the translation build system for addons as well as po files.

		ADDON_DIRECTORY represents the name of the directory that contains the targeted addon, while OUTPUT_DIRECTORY represents the directory where the "po" directory and a few other files belonging to the build system will be dumped.

		Options:

		--help          | -h       Displays this information and exits.
		--verbose       | -v       Enables extra information.

		Version switches:

		--1.0
		--1.2
		--1.4
		--1.6
		--1.8
		--1.10
		--1.12

		This script should be run in the directory that contains the target addon's directory.

		Report any issues to AI0867 and Espreon.


		NOTES FOR ACTUAL USAGE:
		-run the script *from the addon translation repo's root*, that is Invasion_from_the_Unknown-1.10 or the like
		-invoke it as path/to/init-build-sys.sh --1.10 Invasion_from_the_Unknown .
		-DO NOT FORGET THE PERIOD, or it might decide to write to your home directory instead
