[ELDK] need to use GDB/MI commands with gdb provided by ELDK4.1.

I am trying to automate GDB debugging so that I can debug an application in
the lights out mode , the debug script will "test" the application using the
gdb and log the information I need.. This is in the concept stages , but
this is what I am planning to do .

     > Write some scripts may be in shell or otherwise ( I heard of a Tk
module called GDBMI ) which will be automatically able to communicate with
the gdb server running on the target and run commands . and capture data .

I will give an example below of how I need the set upto be automated , this
is assuming that the gdbserver on the target side is started with
application nick_arm and listening to port 12345

  $ arm-linux-gdb nick_arm

(gdb) set solib-absolute-prefix /home/dbasu/ELDK/arm/lib
(gdb) set solib-search-path /home/dbasu/ELDK/arm/lib
(gdb) target remote

I need to have these set of commands automated , this will be my set up
script before I get into the actual automation , I thought GDB/MI interface
is easier to automate hence I thought  above commands need to be written in
MI equivalent of CLI, but I may be wrong here .

Please comment .
