New Revision: 5547

Added:
   plugins/branches/lifetype-1.2/genpluginfeeds.php
Log:
This is a [simple] script that will checkout the given svn branch with plugins, process the plugins that were fetched from CVS and extract things like the version string and the description and then write an RSS 2.0 feed with this information. One of the ideas is that people can subscribe to it to track new plugin releases, but the most important one is that the "Pluugin Centre" page will automatically fetch this file, process it and display a warning message next to the outdated plugins. Hopefully this will help users stay up to date, we've always had problems with users running old and broken versions of plugins so hopefully this will help them a bit...
