From 7e5bbf0387203a078bf901d730f063f10c7c1f2c Mon Sep 17 00:00:00 2001
From: lolilolicon <lolilolicon@gmail.com>
Date: Thu, 6 Oct 2011 14:14:43 +0800
Subject: bacman: bashify using [[ ]] and (( ))

Another style change.  The [[ expression ]] form is particularly
cleaner, safer and more powerful than the [ expression ] form.
