From 16cf6be1ee090093ad99e006b6ffcb9734d779f4 Mon Sep 17 00:00:00 2001
From: erdgeist <>
Date: Sun, 29 Sep 2013 03:52:41 +0000
Subject: Add license. Fix the acutal matching of user and command entries in
 config files. Use -m on su to be able to execute under user priviliges of
 users without a login shell. Use eval before env to expand environment
 variables.
