## Uses a real RCS
Rather than implement its own system for storing page histories etc,
-ikiwiki uses a real RCS. 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

ikiwiki can be run from a [[post-commit]] hook to update your wiki

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.
## A wiki compiler
-ikiwiki is a wiki compiler; it builds static website for your wiki, and
+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)
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]].
+[[plugins/HTML]], or pages written in [[reStructuredText|plugins/rst]]
+or [[Textile|plugins/textile]].
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]]
+## Blogging
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.

Ikiwiki's own [[TODO]], [[news]], and [[plugins]] pages are good examples

+[[example_blog|examples/blog]] set up that you can copy into your own wiki.
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.
-## Valid html and css
+You can also mix blogging with podcasting by dropping audio files where
+they will be picked up like blog posts. This will work for any files that
+you would care to syndicate.

+## Valid html and [[css]]
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.

## [[Plugins]]
Ikiwiki's backend RCS support is also pluggable, so support for new
revision control systems can be added to ikiwiki.
-### [[todo/utf8]]
+The standard language for ikiwiki plugins is perl, but ikiwiki also supports
+[[plugins/write/external]] plugins: Standalone programs that can be written in
+any language and communicate with ikiwiki using XML RPC.
+
+## [[todo/utf8]]
After rather a lot of fiddling, we think that ikiwiki correctly and fully
supports utf8 everywhere.
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.

### Discussion pages
/Discussion subpage. By default, these links are included in the
[[templates]] for each page.
-### Page locking
+### Edit controls
-Wiki admins can lock pages so that only other admins can edit them.
+Wiki admins can [[lock_pages|page_locking]] so that only other admins can
+edit them. Or a wiki can be set up to allow anyone to edit Discussion
+pages, but only registered users to edit other pages. These are just two
+possibilities, since page edit controls can be changed via plugins.
### [[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.
