-;;; Commentary:
-
-;; This mode acts as a graphical user interface to GDB.  You can interact with
-;; GDB through the GUD buffer in the usual way, but there are also further
-;; buffers which control the execution and describe the state of your program.
-;; It separates the input/output of your program from that of GDB, if
-;; required, and watches expressions in the speedbar.  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).
-
-;; By default, M-x gdb will start the debugger.
-
-;; This file has evolved from gdba.el that was included with GDB 5.0 and
-;; written by Tom Lord and Jim Kingdon.  It uses GDB's annotation interface.
-;; You don't need to know about annotations to use this mode as a debugger,
-;; but if you are interested developing the mode itself, see the Annotations
-;; section in the GDB info manual.
-
-;; GDB developers plan to make the annotation interface obsolete.  A new
-;; interface called GDB/MI (machine interface) has been designed to replace it.
-;; Some GDB/MI commands are used in this file through the CLI command
-;; 'interpreter mi <mi-command>'.  To help with the process of fully migrating
-;; Emacs from annotations to GDB/MI, there is an experimental package called
-;; gdb-mi in the Emacs Lisp Package Archive ("http://tromey.com/elpa/").  It
-;; comprises of modified gud.el and a file called gdb-mi.el which replaces
-;; gdb-ui.el.  When installed, this overrides the current files and invoking
-;; M-x gdb will use GDB/MI directly (starts with "gdb -i=mi").  When deleted
-;; ('d' followed by 'x' in Package Menu mode), the files are deleted and old
-;; functionality restored.  This provides a convenient way to review the
-;; current status/contribute to its improvement.  For someone who just wants to
-;; use GDB, however, the current mode in Emacs 22 is a much better option.
-;; There is also a file, also called gdb-mi.el, a version of which is included
-;; the GDB distribution.  This will probably only work with versions
-;; distributed with GDB 6.5 or later.  Unlike the version in ELPA it works on
-;; top of gdb-ui.el and you can only start it with M-x gdbmi.
-
-;; This mode SHOULD WORK WITH GDB 5.0 or later but you will NEED AT LEAST
-;; GDB 6.0 to use watch expressions.  It works best with GDB 6.4 or later
-;; where watch expressions will update more quickly.
-
-;;; Windows Platforms:
-
-;; If you are using Emacs and GDB on Windows you will need to flush the buffer
-;; explicitly in your program if you want timely display of I/O in Emacs.
-;; Alternatively you can make the output stream unbuffered, for example, by
-;; using a macro:
-
-;;           #ifdef UNBUFFERED
-;;	     setvbuf (stdout, (char *) NULL, _IONBF, 0);
-;;	     #endif
-
-;; and compiling with -DUNBUFFERED while debugging.
-
-;; If you are using Cygwin GDB and find that the source is not being displayed
-;; in Emacs when you step through it, possible solutions are to:
-
-;;   1) Use Cygwin X Windows and Cygwin Emacs.
-;;        (Since 22.1 Emacs builds under Cygwin.)
-;;   2) Use MinGW GDB instead.
-;;   3) Use cygwin-mount.el
-
-;;; Mac OSX:
-
-;; GDB in Emacs on Mac OSX works best with FSF GDB as Apple have made
-;; some changes to the version that they include as part of Mac OSX.
-;; This requires GDB version 7.0 or later (estimated release date June 2009)
-;; as earlier versions don not compile on Mac OSX.
-
-;;; Known Bugs:
-
-;; 1) Cannot handle multiple debug sessions.
-;; 2) If you wish to call procedures from your program in GDB
-;;    e.g "call myproc ()", "p mysquare (5)" then use level 2 annotations
-;;    "gdb --annotate=2 myprog" to keep source buffer/selected frame fixed.
-;; 3) After detaching from a process, clicking on the "GO" icon on toolbar
-;;    (gud-go) sends "continue" to GDB (should be "run").
-
-;;; TODO:
-
-;; 1) Use MI command -data-read-memory for memory window.
-;; 2) Use tree-buffer.el (from ECB) instead of the speedbar for
-;;    watch-expressions?  Handling of watch-expressions needs to be
-;;    overhauled to work for large arrays/structures by creating variable
-;;    objects for visible watch-expressions only.
-;; 3) Mark breakpoint locations on scroll-bar of source buffer?
