/*
Git Revision Number Updater for Footer

	This is probably a pretty awful, hacky, way to have the git commit number/hash thing
	put in the footer. We have to run this script manually on each (significant) commit,
	but at least it gives us some way of tracking git revision versions in the footer
	of Amalia admin pages, when debug is on.
	
	This file is therefore meant to be run only via CLI, in the context of the git repository.
	You should probably remove it from your web-based installation.
	
	I realise this is probably not the best solution -- but many others I researched looked
	worse. :(
