+
+This plugin allows ikiwiki to push generated pages to another host
+by running a command such as `rsync`.
+
+### Usage
+7. Enable automated SSH key exchange between ikiwiki and the remote
+   host. [keychain](http://www.gentoo.org/proj/en/keychain/) makes
+   it easy to use a passphrase-protected key for this purpose. It's
+   also a good idea to specify the exact command line to be permitted
+   in the remote host's `$HOME/.ssh/authorized_keys`.
+7. Set `rsync_command` in your setup file. If you're using a
+   passphrase-protected key, then set `rsync_command` to a shell
+   script which reads `keychain`'s current state before calling
+   `rsync`.
+
+### Implementation details
+* The plugin relies on a new "postrefresh" hook called at the very end of
+  `IkiWiki/Render.pm:refresh()`.

+## A use case
+
+Why I needed this plugin: I have two web servers available to me
+for a project. Neither does everything I need, but together they
+do. (This is a bit like the [Amazon S3
+scenario](http://kitenet.net/~joey/blog/entry/running_a_wiki_on_Amazon_S3/).)
+
+Server (1) is a university web server. It provides plentiful space
+and bandwidth, easy authentication for people editing the wiki, and
+a well-known stable URL. The wiki really wants to live here and
+very easily could except that the server doesn't allow arbitrary
+CGIs.
+
+Server (2) is provided by a generous alumnus's paid [[tips/DreamHost]]
+account. Disk and particularly network usage need to be minimized
+because over some threshold it costs him. CGI, etc. are available.
+
+My plan was to host the wiki on server (1) by taking advantage of
+server (2) to store the repository, source checkout, and generated
+pages, to host the repository browser, and to handle ikiwiki's CGI
+operations. In order for this to work, web edits on (2) would need
+to automatically push any changed pages to (1).
+
+As a proof of concept, I added an rsync post-commit hook after
+ikiwiki's usual. It worked, just not for web edits, which is how
+the wiki will be used. So I wrote this plugin to finish the job.
+The wiki now lives on (1), and clicking "edit" just works. --[[schmonz]]

 Most of the options, like `wikiname` in the setup file are the same as
-ikiwiki's command line options (documented in [[usage]]. `srcdir` and
+ikiwiki's command line options (documented in [[usage]]). `srcdir` and
