+* --setup configfile
+
+ In setup mode, ikiwiki reads the config file, which is really a perl
+ program that can call ikiwiki internal functions. Uses of this are
+ various; the normal one is to automatically generate wrappers for a
+ wiki based on data in a config file.
+
+ Note that the wiki will be (re)built as part of the setup process to
+ ensure that any changes take effect.
+
+ [[ikiwiki.setup]] is an example of such a config file.
