+is a minimal markup language that resembles plain text as used in
+email messages. It is the markup language used by this wiki.

+For documentation about the markdown syntax, see

+Note that [[WikiLink]]s are not part of the markdown syntax, and are the
+only bit of markup that this wiki handles internally.
