To install through the plugin manager use http://ryanschwartz.net/dokuwiki_textile2.tgz. To install manually, create a textile2 directory inside your plugins directory, and in put both the below php as syntax.php, and https://github.com/johnstephens/textile/blob/master/classTextile.php into it.

Any possibility of just uploading that here and linking it for a centralized location?

To use textile markup in your page, mark an area in a textile block. For example:

<textile>

h1. Hi
</textile>

will result in a textile rendering of an h1 header saying “Hi”. Note the newline following the first textile, that seems to be a requirement of the plug-in.
