+# * n — no external messages, you must be on the channel to message it.
+# * t — you must be hop or higher to change topic
+# * g — anyone can /invite
+#     * InspIRCd: +g blocks messages matching the given glob mask - if
+#       empty not set, I think
+# * C — block CTCPs to channel
+# * A — InspIRCd: anyone can /invite
+#    * Charybdis: Admin-only, but this MLOCK does nothing to me, so I am
+#    * ignoring it.
+# * T — InspIRCd: blocks notices from users who aren't at least HOP
+#
+# * i — invite-only
+# * l — limit maximum number of people on the channel
+# * k — key/password for joining the channel
+# Other nice modes (not set by this script): Charybdis +rS / InspIRCd: +Rz
