* Name: Subversion Updater
* Author: Shish <webmaster@shishnet.org>
* License: GPLv2
* Description: Provides a button to check for updates
* Documentation:
* This is a very risky idea, implemented without safeguards.
* If you've done a clean SVN checkout, then updating will
* normally work fine; but if you've made changes in one way,
* and SVN has changed something in a different way, then there
* will be conflicts and the site will die :(
