	<description>
        GATE - general architecture for text engineering - is open source
        software capable of solving almost any text processing problem.  This
        artifact enables you to embed the core GATE Embedded with its essential
        dependencies.  You will able to use the GATE Embedded API and load and
        store GATE XML documents. This artifact is the perfect dependency for
        CREOLE plugins or for applications that need to customize the GATE
        dependencies due to conflict with their own dependencies or for lower
        footprint.
