XML-RPC Update Check

You can query core, plugin, and themes individually, or check all at once.

It defines four new methods:

• xmlrpcCoreUpdateCheck — checks core, returns true/false
• xmlrpcPluginUpdateCheck — checks plugins, returns true/false
• xmlrpcThemeUpdateCheck — checks themes, returns true/false
• xmlrpcUpdatesCheck — checks all of the above, returns an array of trues/falses.

The plugin was created primarily for WPUpCheck (http://trog.qgl.org/wpupcheck/), a simple Windows application that remotely polls a WordPress site to see if updates are available.
