+# This script simply checks the status of the certificates used by
+# Qmail with Frederik Vermeulen's TLS patch - to ensure they are
+# valid, non-expired certs with the appropriate KeyUsage extensions
+# required to get their jobs done.
+# This script can be run on a nightly basis to check the cert status.
+# Note that when it marked as cert as "bad" (typically because it's
+# expired), it will be renamed, a syslog event generated, and probably
+# Qmail will STOP WORKING FOR NEW TLS SESSIONS.
+#
+# That may sound bad, but the alternative is that Qmail will stop working
+# for new TLS sessions *anyway* - it's just that this script will tell
+# you why...
