 Preprocessor directives which already use the new syntax will remain
 unchanged.

 older versions of ikiwiki accepted, the prefix_directives transition will
 treat these as preprocessor directives and convert them.
 
+One other transition is handled, the `indexdb` mode handles converting
+a plain text `.ikiwiki/index` file to a binary `.ikiwiki/indexdb`. In this
+mode, you should specify the srcdir of the wiki as the second parameter.
+You do not normally need to run `ikiwiki-transition indexdb`; ikiwiki will
+automatically run it as necessary.
