   "It is often necessary to keep track of an arbitrary set of SimObjects. "
   "For instance, Torque's networking code needs to not only keep track of "
   "the set of objects which need to be ghosted, but also the set of objects "
   "which must <i>always</i> be ghosted. It does this by working with two "
   "sets. The first of these is the RootGroup (which is actually a SimGroup) "
   "and the second is the GhostAlwaysSet, which contains objects which must "
   "always be ghosted to the client.\n\n"

   "Some general notes on SimSets:\n\n"
   "- Membership is not exclusive. A SimObject may be a member of multiple "
   "SimSets.\n\n"
   "- A SimSet does not destroy subobjects when it is destroyed.\n\n"
   "- A SimSet may hold an arbitrary number of objects.\n\n"

   "of a single SimGroup at a time. The SimGroup will automatically enforce "
   "the single-group-membership rule (ie. adding an object to a SimGroup will "
   "cause it to be removed from its current SimGroup, if any).\n\n"
