+"""RCS Proxy.
+
+Provide a simplified interface on RCS files, locally or remotely.
+The functionality is geared towards implementing some sort of
+remote CVS like utility.  It is modeled after the similar module
+FSProxy.
+
+The module defines two classes:
+
+RCSProxyLocal  -- used for local access
+RCSProxyServer -- used on the server side of remote access
+
+The corresponding client class, RCSProxyClient, is defined in module
+rcsclient.
+
+The remote classes are instantiated with an IP address and an optional
+verbosity flag.
