 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,
+  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

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