+# IRCv3 module: Provides the following IRCv3.1 extensions:
+# extended-join, away-notify and account-notify. These are optional
+# enhancements to the client-to-server protocol. An extension is only
+# active for a client when the client specifically requests it, so this
+# module needs m_cap to work.
+# 
+# Further information on these extensions can be found at the IRCv3
+# working group website:
+# http://ircv3.atheme.org/extensions/

+# The following block can be used to control which extensions are
+# enabled.
