From 4316e77e1eb6654eec18d04780a6da78c22fb644 Mon Sep 17 00:00:00 2001
From: Reinier Zwitserloot <reinier@tipit.to>
Date: Fri, 27 Nov 2009 07:18:48 +0100
Subject: Added a class that is easier to use than the parser itself for
 delombok, as well as code to process entire directories at a time. Also
 removed duplication from the testcases.
