From fccb39dcd85edb30532bf4a6e6dfb056d40bc522 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Tue, 9 Oct 2007 23:50:11 -0500 Subject: A bunch of those first-glance type updates Some new eyes on the code, and finding some new things to fix up. A lot of documentation type stuff with some code commenting. Make the message and echo stuff a bit more consistant. Move the UID check later so that we can see help as a normal user. Other small fixups.
