Subject: [PATCH] write only
Date: Thu, 12 Feb 2004 04:08:00 -0800 (PST)

I've added a write only option to rsyncd.conf which is essentially the opposite
of read only.  This means that although it's possible someone on our allowed IP
range could overwrite (or delete) files on the rsync share, they would not be
allowed to download any files (my primary concern).
