-Another, separate plugin system that already (mostly) exists in ikiwiki is the RCS backend, which allows writing modules to drive other RCS systems than subversion.

-## preprocessor plugins
-
-Considering ikiwiki plugins, one idea I have is to make the [[PreProcessorDirective]]s be a plugin. A setting in the config file would enable various plusins, which are perl modules, that each provide one or more preprocessor directives.
-
-Since preprocessing happens before htmlization but after a page is loaded and linkified, it should be possible to use it to create something like a link map or lists, or a page index. Page inlining and rss generation is already done via preprocessor directives and seems a natureal as a plugin too.
-
-Note that things like a link map or a broken link list page would need to
-be updated whenever a set (or all) pages change; the %depends hash
-already allows for pages to register this, although there could be some
-strange behavior if mixing multiple directives some of which exclude pages
-that others might want to include.
-
-I need to look at the full range of things that other wikis use their plugin systems for, but preprocessor directives as plugins certianly seems useful, even if it's not a complete solution.
