+// This class is used to virtualize a ConVar's value, so the client can restrict its 
+// value while connected to a server. When using this across modules, it's important
+// to dynamic_cast it to a ConVar_ServerBounded or you won't get the restricted value.
+//
+// NOTE: FCVAR_USERINFO vars are not virtualized before they are sent to the server
+//       (we have no way to detect if the virtualized value would change), so
+//       if you want to use a bounded cvar's value on the server, you must rebound it
+//       the same way the client does.
