       The rrrrddttooooll functions are directly callable via the Python programming
       language. This wrapper implementation has been written from the scratch
       (without  SWIG)

       The API expects strings and/or a list of strings as parameters to the
       functions.  Please refer to the other rrrrddttooooll documentation for
       functions and valid arguments.

       If you use the ssiittee--ppyytthhoonn--iinnssttaallll make target you can drop to first
       sys.path.append line since the RRDtool module will be available
       everywhere.

       If RRDtool runs into trouble, it will throw an exception which you
       might want to catch.
