        This is a NAnt build script that checks the version.

        For debugging open a command line prompt and type:

        > cd (path to this project)
        > nant.exe -buildfile:test\nant.check-version.xml

    <!-- 1. Define the variables (ie 'properties' in nant-speak) we will be using -->

    <!-- 2. Check the version -->
