* TransformingProjectBuilder
    - Performs an XSL transform on all ".xml" build files.
    - Identity transform is used for projects with "version" attribute.
    - Added xalan.jar to lib - replaced jaxp.jar with xml-apis.jar

* Compatibility Layer
    - Described more fully in src/ant1compat/README.txt
    - Uses pre-compiled Ant1 jar files for Ant1 code-base.
      Insulates from changes in the main tree, and simplifies build.
    - "ant." prefix used for all ant1 tasks
