From da9e282d834f0e2128501a8154128dc95b4c599d Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add a script to generate component.xml files.
plexus-component-metadata is normally used for this task, but it
depends on maven-core, which depends on maven-model-builder, which needs
plexus-component-metadata. This script is meant to break this dependency
cycle.
