    Abstract superclass for sourceCodeManagers.

    Concrete subclasses provide access to a source repository.

    Most protocol here traps into subclassResponsbility errors.

    Please read more documentation in concrete subclasses 

    (especially: CVSSourceCodeManager) for how to use this manager and

    what to redefine in another repository manager if required.
