 """ClusterMsgs module: Message types for Cluster rendering"""
 
+# This module is intended to supply routines and dataformats common to
+# both ClusterClient and ClusterServer.  There is a bit of sloppiness
+# though.  For example:
+#    This is where datagrams are constructed for sending, but datagrams
+#    recieved are handled outside of here, after the header (message type
+#    and number) are read here.
+
+#these are the types of messages that are currently supported.
