+// Details: MI driver base implementation class. This class has been created so
+// not have to edit the lldb::SBBroadcaster class code. Functionality
+// and attributes need to be common to the LLDB Driver class and the
+// MI Driver class (derived from lldb::SBBroadcaster) so they can call
+// upon each other for functionality fall through and allow the
+// CDriverMgr to manage either (any) driver to be operated on.
+// Each driver instance (the CMIDriver, LLDB::Driver) has its own
+// LLDB::SBDebugger object.
+// Gotchas: None.
