From 3ca575c5d44de0214b54c63eb99ca0cbd8bbd13c Mon Sep 17 00:00:00 2001
From: Mark Huang <mlhuang@cs.princeton.edu>
Date: Sat, 20 Jan 2007 04:02:43 +0000
Subject: [PATCH] - create a build user with the same uid/gid as the sudoer, if
   possible. Set its home directory to /data/build. - skip the whole cvs
 import garbage; too confusing and no one uses it
