-* --setup configfile

-  In setup mode, ikiwiki reads the config file, which is really a perl
-  program that can call ikiwiki internal functions.
+  If the [[plugins/aggregate]] plugin is enabled, this makes ikiwiki poll
+  configured feeds and save new posts to the srcdir.

 
 

-  The default action when --setup is specified is to automatically generate
-  wrappers for a wiki based on data in a config file, and rebuild the wiki.
+  Note that to rebuild previously aggregated posts, use the --rebuild option
+  along with this one. --rebuild will also force feeds to be polled even if
+  they were polled recently.

 
 

-  [[ikiwiki.setup]] is an example of such a config file.
+* --render file

 
 

-* --wrappers
+  Renders a single file, outputting the resulting html. Does not save state,
+  so this cannot be used for building whole wikis, but it is useful for
+  previewing an edited file at the command line. Generally used in conjunction
+  with --setup to load in a wiki's setup:

 
 

-  If used with --setup --refresh, this makes it also update any configured

+  Run in post-commit mode, the same as if called by a [[post-commit]] hook.
+  This is probably only useful when using ikiwiki with a web server on one host
