+Maven 1.x Integration
+
+This component will internally spawn a complete Maven 1.x instance
+that will run a project from within m2, using a specified version of
+Maven 1.x.
+
+This will allow a mix of m2 and m1 projects in a single organization
+with only one installation, aiding the transition.
+
+Work in progress, Brett Porter, 18/8/04
+
+
+Currently it does require an m1 installation to obtain the plugins installed. It could potentially use
+the plugin descriptor file for this.
