   * replaced "#!/bin/bash" with "#!/usr/bin/env bash" for better
     portability.
   * fixed busted lockfile arrangement, where empty file was being locked
-  * portability fixes for date, mktemp, hostname
+  * portability fixes in the way we use date, mktemp, hostname, su
+  * stop using stat, since the syntax appears to be totally unportable
+  * require GNU getopt, and test for getopt failures (look for getopt in
+    /usr/local/bin first, since that's where FreeBSD's GNU-compatible
+    getopt lives.
