+"""File System Proxy.
+
+Provide an OS-neutral view on a file system, locally or remotely.
+The functionality is geared towards implementing some sort of
+rdist-like utility between a Mac and a UNIX system.
+
+The module defines three classes:
+
+FSProxyLocal  -- used for local access
+FSProxyServer -- used on the server side of remote access
+FSProxyClient -- used on the client side of remote access
+
+The remote classes are instantiated with an IP address and an optional
+verbosity flag.
