// Overview:    CMICmdCmdGdbSet 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 MI command "gdb-set".
//          This command does not follow the MI documentation exactly. While
//          *this
//          command is implemented it does not do anything with the gdb-set
//          variable past in.
//          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.
