Zd�Zd�ZRS(s7RCS interface class (local filesystem version).

    An instance of this class represents a directory with rcs version
    files and (possible) corresponding work files.

    Methods provide access to most rcs operations such as
    checkin/checkout, access to the rcs metadata (revisions, logs,
    branches etc.) as well as some filesystem operations such as
    listing all rcs version files.

    XXX BUGS / PROBLEMS

    - The instance always represents the current directory so it's not
    very useful to have more than one instance around simultaneously
