+* --setup setupfile
+
+ 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.
+
+* --changesetup setupfile
+
+ Reads the setup file, adds any configuration changes specified by other
+ options, and writes the new configuration back to the setup file. Also
+ updates any configured wrappers. In this mode, the wiki is not fully
+ rebuilt, unless you also add --rebuild.
+
+ Example, to enable some plugins:
+
+ ikiwiki --changesetup ~/ikiwiki.setup --plugin goodstuff --plugin calendar
+
+* --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.
