+An overview of some of ikiwiki's features:
+[[toc ]]
-* [[Subversion]]
+## Uses a real RCS
- Rather than implement its own system for storing page histories etc, ikiwiki simply uses subversion. (Supporting other revision control systems is also possible, ikiwiki only needs $FOO add, $FOO commit, and $FOO log).
+Rather than implement its own system for storing page histories etc,
+ikiwiki uses a real Revision Control System. This isn't because we're
+lazy, it's because a real RCS is a good thing to have, and there are
+advantages to using one that are not possible with a standard wiki.
- Instead of editing pages in a stupid web form, you can use vim and commit changes via svn. Or work disconnected using svk and push your changes out when you come online. Deal with edit conflicts with others in a sane environment. Take advantage of subversion's smart merges.

+to work in a distributed fashion all the time. (It's also possible to
+[[plugins/write]] a plugin to support other systems.)
- ikiwiki can be run from a [[post-commit]] hook to update your wiki immediately whenever you commit.

-* [[MarkDown]]
+Note that ikiwiki does not require a RCS to function. If you want to
+run a simple wiki without page history, it can do that too.
- ikiwiki supports pages using [[MarkDown]] as their markup language. Any
- page with a filename ending in ".mdwn" is converted from markdown to html
- by ikiwiki. Markdown understands text formatted as it would be in an email,
- and is quite smart about converting it to html. The only additional markup
- provided by ikiwiki aside from regular markdown is the [[WikiLink]].
+## A wiki compiler
-* support for other file types
+ikiwiki is a wiki compiler; it builds a static website for your wiki, and
+updates it as pages are edited. It is fast and smart about updating a wiki,
+it only builds pages that have changed (and tracks things like creation of
+new pages and links that can indirectly cause a page to need a rebuild)
- ikiwiki also supports files of any other type, including raw html, text,
- images, etc. These are not converted to wiki pages, they are just copied
- unchanged by ikiwiki as it builds your wiki. So you can check in an image,
- program, or other special file and link to it from your wiki pages.
+## Supports many markup languages
-* [[SubPage]]s
+By default, pages in the wiki are written using the [[MarkDown]] format.
+Any page with a filename ending in ".mdwn" is converted from markdown to html
+by ikiwiki. Markdown understands text formatted as it would be in an email,
+and is quite smart about converting it to html. The only additional markup
+provided by ikiwiki on top of regular markdown is the [[WikiLink]] and
+[[PreprocessorDirective]].
- Arbitrarily deep hierarchies of pages with fairly simple and useful [[SubPage/LinkingRUles]]
+If you prefer to use some other markup language, ikiwiki allows others to
+easily be added by [[plugins]]. For example it also supports traditional
+[[plugins/WikiText]] formatted pages, pages written as pure
+[[plugins/HTML]], or pages written in [[reStructuredText|plugins/rst]].
-* Fast compiler
+ikiwiki also supports files of any other type, including plain text,
+images, etc. These are not converted to wiki pages, they are just copied
+unchanged by ikiwiki as it builds your wiki. So you can check in an image,
+program, or other special file and link to it from your wiki pages.

+## [[Blogging|blog]]
-* [[BackLinks]]
+You can turn any page in the wiki into a [[blog]]. Pages matching a
+specified [[PageSpec]] will be displayed as a weblog within the blog
+page. And an RSS feed can be generated to follow the blog.
- Automatically included on pages. Rather faster than eg [[MoinMoin]] and always there to help with navigation.
+Ikiwiki's own [[TODO]], [[news]], and [[plugins]] pages are good examples
+of some of the flexible ways that this can be used.
-* [[PageHistory]]
+Ikiwiki can also [[plugins/aggregate]] external blogs, feeding them into
+the wiki. This can be used to create a Planet type site that aggregates
+interesting feeds.
- Well, sorta. Rather than implementing YA history browser, it can link to [[ViewCVS]] or the link to browse the history of a wiki page.
+## Valid html and css
-* [[RecentChanges]], editng pages in a web browser
+ikiwiki aims to produce
+[valid XHTML 1.0](http://validator.w3.org/check?url=referer).
+ikiwiki generates html using [[templates]], and uses css, so you can
+change the look and layout of all pages in any way you would like.
- Nearly the definition of a wiki, although perhaps ikiwiki challenges how much of that web gunk a wiki really needs. These features are optional and can be enabled by enabling [[CGI]].
+## [[Plugins]]
-----
+Plugins can be used to add additional features to ikiwiki. The interface
+is quite flexible, allowing plugins to implement additional markup
+languages, register [[PreProcessorDirective]]s, hook into [[CGI]] mode,
+and more. Most of ikiwiki's features are actually provided by plugins.
+Ikiwiki's backend RCS support is also pluggable, so support for new
+revision control systems can be added to ikiwiki.
-It also has lots of [[TODO]] items and [[Bugs]]. This wiki is not ready for production!
\ No newline at end of file
+## [[todo/utf8]]
+
+After rather a lot of fiddling, we think that ikiwiki correctly and fully
+supports utf8 everywhere.
+
+## Other features
+
+The above are the core design goals and features of ikiwiki, but on that
+foundation a lot of other important features are added. Here is an
+incomplete list of some of them.
+
+### [[Tags]]
+
+You can tag pages and use these tags in various ways. Tags will show
+up in the ways you'd expect, like at the bottom of pages, in blogs, and
+in rss feeds.
+
+### [[SubPages|SubPage]]
+
+Arbitrarily deep hierarchies of pages with fairly simple and useful
+[[SubPage/LinkingRules]]
+
+### [[BackLinks]]
+
+Automatically included on pages. Rather faster than eg MoinMoin and
+always there to help with navigation.
+
+### Smart merging and conflict resolution in your web browser
+
+Since it uses a real RCS, ikiwiki takes advantage of its smart merging to
+avoid any conflicts when two people edit different parts of the same page
+at the same time. No annoying warnings about other editors, or locking,
+etc, instead the other person's changes will be automatically merged with
+yours when you commit.
+
+In the rare cases where automatic merging fails due to the same part of a
+page being concurrently edited, regular commit conflict markers are
+shown in the file to resolve the conflict, so if you're already familiar
+with that there's no new commit marker syntax to learn.
+
+### [[RecentChanges]], editing pages in a web browser
+
+Nearly the definition of a wiki, although perhaps ikiwiki challenges how
+much of that web gunk a wiki really needs. These features are optional
+and can be enabled by enabling [[CGI]].
+
+### User registration
+
+Can optionally be configured to allow only registered users to post
+pages; online user registration form, etc.
+
+### Discussion pages
+
+Thanks to subpages, every page can easily and automatically have a
+/Discussion subpage. By default, these links are included in the
+[[templates]] for each page.
+
+### Page locking
+
+Wiki admins can lock pages so that only other admins can edit them.
+
+### [[PageHistory]]
+
+Well, sorta. Rather than implementing YA history browser, it can link to
+[[ViewCVS]] or the like to browse the history of a wiki page.
+
+### Full text search
+
+ikiwiki can use the [[HyperEstraier]] search engine to add powerful
+full text search capabilities to your wiki.
+
+### Commit mails
+
+ikiwiki can be configured to send you commit mails with diffs of changes
+to selected pages.
+
+### [[w3mmode]]
+
+Can be set up so that w3m can be used to browse a wiki and edit pages
+without using a web server.
