Version File Autodiscovery
To simplify the process of using Plugin Manager, plugin authors can publish an “mt-installer” link relation in the header of their plugin’s homepage that points to the plugin’s version.xml file. For example:
<link rel="mt-installer" href="http://example.com/projects/PluginX/version.xml" />
This allows users to specify the plugin’s homepage in the Plugin Manager installation process instead of having to find or remember the download link. This link relation is optional, but highly recommended.
