  <!-- Activating any of these profiles will cause the python PB bindings package
  to be built. The profiles can be activated in any of 3 ways:

    * -DPYTHON_BINDINGS on the command line (e.g., "mvn install -DPYTHON_BINDINGS")
    * Defining the PYTHON_BINDINGS environment variable.

Otherwise, no package will be built and developers don't not need to worry about having
python installed, if they don't need python bindings.
