-// Overview: Defines the entry point for the console application.
-// The MI application (project name MI) runs in two modes:
-// An LLDB native driver mode where it acts no different from the
-// LLDB driver.
-// The other mode is the MI when it finds on the command line
-// the --interpreter option. Command line argument --help on its
-// own will give
-// help for the LLDB driver. If entered with --interpreter then MI
-// help will
-// provided.
-// To implement new MI commands derive a new command class from the
-// command base
-// class. To enable the new command for interpretation add the new
-// command class
-// to the command factory. The files of relevance are:
-// MICmdCommands.cpp
