+# instant-rsyncd lets you quickly set up and start a simple, unprivileged rsync
+# daemon with a single module in the current directory.  I've found it
+# invaluable for quick testing, and I use it when writing a list of commands
+# that people can paste into a terminal to reproduce a daemon-related bug.
+# Sysadmins deploying an rsync daemon for the first time may find it helpful as
+# a starting point.
+#
+# Usage: instant-rsyncd MODULE PORT RSYNCD-USERNAME [RSYNC-PATH]
+# The script asks for the rsyncd user's password twice on stdin, once to set it
+# and once to log in to test the daemon.
+# -- Matt McCutchen <matt@mattmccutchen.net>
