+* --setup setupfile
+
+ In setup mode, ikiwiki reads the config file, which is really a perl
+ program that can call ikiwiki internal functions.
+
+ The default action when --setup is specified is to automatically generate
+ wrappers for a wiki based on data in a setup file, and rebuild the wiki.
+ If you only want to build any changed pages, you can use --refresh with
+ --setup.
+
+* --dumpsetup setupfile
+
+ Causes ikiwiki to write to the specified setup file, dumping out
+ its current configuration.
+
+* --wrappers
+
+ If used with --setup --refresh, this makes it also update any configured
+ wrappers.
+
+* --clean
+
+ This makes ikiwiki clean up by removing any files it denerated in the
+ `destination` directory, as well as any configured wrappers, and the
+ `.ikiwiki` state directory. This is mostly useful if you're running
+ ikiwiki in a Makefile to build documentation and want a corresponding
+ `clean` target.
