-`ikiwiki` is a wiki compiler. It builds static html pages for a wiki, from

 Note that most options can be shortened to single letters, and boolean
 flags such as --verbose can be negated with --no-verbose.

-  If you also pass the --refresh option, ikiwiki will instead just refresh

+
+* --render file
+
+  Renders a single file, outputting the resulting html. Does not save state,

+
+  Run in post-commit mode, the same as if called by a [[post-commit]] hook.
