  <description><![CDATA[
    Maven 4 Plugin descriptor, stored in {@code META-INF/maven/plugin.xml} in a plugin's jar artifact.
    This descriptor is generally using the information contained in the annotations of the plugin api.

  the component descriptor and when it's loaded we can add the discoverer, that would be simpler. I could
  also do this with the lister as well
i'l
// 1 the metadata -> model plugin/mojo descriptor
// 2 tools for doing the mapping
// 3 the component model -> interfaces for the plugin

// The plugin manager should load up a directory structure of plugins.
