;; This file is part of GNU GDB.
;;; Commentary:
-;; This mode acts as a graphical user interface to GDB and requires GDB 6.1
-;; onwards. You can interact with GDB through the GUD buffer in the usual way,
-;; but there are also buffers which control the execution and describe the
-;; state of your program. It separates the input/output of your program from
-;; that of GDB and displays expressions and their current values in their own
-;; buffers. It also uses features of Emacs 21 such as the fringe/display
-;; margin for breakpoints, and the toolbar (see the GDB Graphical Interface
-;; section in the Emacs info manual).

+;; used in gdb-ui.el) to GDB/MI. It runs gdb with GDB/MI (-interp=mi) and
+;; access CLI using "-interpreter-exec console cli-command".
+;;
;; Known Bugs:
;;
-
+;; 1) To handle program input, if required, and to avoid extra output in the
+;; GUD buffer you must not use run, step, next or continue etc but their MI
+;; counterparts through gud-run, gud-step etc, e.g clicking on the appropriate
+;; icon in the toolbar.
+;;
+;; 2) Some commands send extra prompts to the GUD buffer.
+;;
+;; TODO:
+;; 1) Prefix MI commands with a token instead of queueing commands.
+;; 2) Use MI command -data-read-memory for memory window.
+;; 3) Use MI command -data-disassemble for disassembly window.
+;; 4) Allow separate buffers for Inferior IO and GDB IO.
+;; 5) Watch windows to work with threads.
