  <description>
    Check Ants codebase against certain code styleguide rules using
    checkstyle and simian.

    Checkstyle uses an abstract syntax tree (AST) for doing checks
    against java sources. It is available at http://checkstyle.sourceforge.net/
    under GPL 2.1 license.

    "Simian (Similarity Analyser) identifies duplication in Java, C#, C,
    CPP, COBOL, JSP, HTML source code and even plain text files."
    It is available at http://www.redhillconsulting.com.au/products/simian/
    and is for free use in open source projects.

    See external task page and homepages for more information.
