// Overview: CMICmdCmdGdbInfo interface.
//
// 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
// MICmdBase.h / .cpp
// MICmdCmd.h / .cpp
// For an introduction to adding a new command see CMICmdCmdSupportInfoMiCmdQuery
// command class as an example.

// Details: MI command class. MI commands derived from the command base class.
// *this class implements GDB command "info".
// The design of matching the info request to a request action (or
// command) is very simple. The request function which carries out
// the task of information gathering and printing to stdout is part of
// *this class. Should the request function become more complicated then
// that request should really reside in a command type class. Then this
// class instantiates a request info command for a matching request. The
// design/code of *this class then does not then become bloated. Use a
// lightweight version of the current MI command system.
// Gotchas: None.

// Changes: None.
