+  *   set up to accept 3 types of initialization.
+  *
+  *   1) Raw message - All data is carried in the byte pointer aMessage,
+  *      args 2,3,4 should be set to TM_NO_ID and aLength 
+  *      must be set to the full length of aMessage, including null
+  *      termination if the payload is a null-term string and the size of the
+  *      tmHeader struct preceeding the message. Currently this
+  *      format is used at the IPC boundary, where we receive a byte pointer
+  *      from the IPC Daemon.
+  *
+  *   2) Flags only - aQueueID, aAction and aStatus are all set. aMessage
+  *      should be set to nsnull and aLength to 0. This format is used when
+  *      sending reply messages (except for ATTACH_REPLY) and when the TS
+  *      Transaction Service is sending "control" messages to the Manager -
+  *      flush, detach, etc...
+  *
+  *   3) Flags and message - All arguements are set. The aMessage is only
+  *      the message for the client app. aLength should be set to the length
+  *      of aMessage and not include the length of the tmHeader struct.
+  *   
+  *   The only data member you can set post initialization is the QueueID.
+  *      You should only call Init() once in the lifetime of a tmTransaction
+  *      as it doesn't clean up the exisiting data before assigning the new
+  *      data. Therefore it would leak most heinously if Init() were to be
+  *      called twice.
+  *
+  *   mOwnerID only has relevance on the IPC daemon side of things. The 
+  *      Transaction Service has no knowledge of this ID and makes no use
+  *      of it.

+// XXX documentation needs work
+//////////////////////////////////////////////////////////////////////////////
+//  Overview of TransactionManager IPC Module
+//
+// Classes:
+//    tmIPCModule - From the tmTransactionManager's point of view, this
+//        is a proxy for the IPC daemon itself. The reverse is true
+//        from the daemon's point of view. This is an interface for the
+//        Transaction system to work with the IPC daemon as its transport
+//        layer.
+//    tmTransactionManager (TM) - Manages the different queues. Maintains
+//        the queues neccessary for different clients. Receives messages
+//        from the tmIPCModule and passes message to the IPC daemon through
+//        the tmIPCModule.
+//    tmQueue - this class manages the transactions for the different areas
+//        of the profiles being shared. Broken down by functional area there
+//        will be  a queue for prefs, cookies etc, but not for profileA and 
+//        profileB, and not for pref_delete, pref_create, pref_change etc...
+//    tmTransaction - the actual transaction being shared with the different
+//        tmClients. It contains the type of transaction, which will equate with
+//        a type of queue in existance, the owner of the transaction (an IPC daemon ID)
+//        and the actual text message to be shared. 
+//
+//////////////////////////////////////////////////////////////////////////////
+
+/// XXX some docs that need to be put somewhere:
+//
+// from tmqueue.cpp
+// Docs - note that the status of the TM_ATTACH_REPLY is only for checking
+//            for TM_ERROR_FAILURE. Other numbers have no importance
+// success of the status means the NS_ERROR_GET_CODE(status) will 
+//     yield the index of the listener.
+//
+// move to documentation page - from tmqueue.h
+//
+// a queue is specific to profile
+//
+// UUID going out from the module is a handler in the client 
+//          (will go to the XPCOM service impling that UUID)
+//   -- does it make sense to have different UUIDs for cookies/prefs/etc
+//
