-;;; 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 and displays
-;; expressions and their current values in their own buffers. It also uses
-;; features of Emacs 21 such as the display margin for breakpoints, and the
-;; toolbar (see the GDB Graphical Interface section in the Emacs info manual).
-
-;; Start the debugger with M-x gdba.
-
-;; This file has evolved from gdba.el from GDB 5.0 written by Tom Lord and Jim
-;; Kingdon and 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, then see the Annotations section in the GDB
-;; info manual. Some GDB/MI commands are also used through th CLI command
-;; 'interpreter mi <mi-command>'.

-The directory containing FILE becomes the initial working directory
-and source-file directory for your debugger.
-
-If `gdb-many-windows' is nil (the default value) then gdb starts with
-just two windows : the GUD and the source buffer. If it is t the
-following layout will appear (keybindings given in relevant buffer) :
-
----------------------------------------------------------------------
- GDB Toolbar
----------------------------------------------------------------------
-GUD buffer (I/O of GDB) | Locals buffer
- |
- |
- |
----------------------------------------------------------------------
-Source buffer | Input/Output (of debuggee) buffer
- | (comint-mode)
- |
- |
- |
- |
- |
- |
----------------------------------------------------------------------
-Stack buffer | Breakpoints buffer
- RET gdb-frames-select | SPC gdb-toggle-breakpoint
- | RET gdb-goto-breakpoint
- | d gdb-delete-breakpoint
----------------------------------------------------------------------
-
-All the buffers share the toolbar and source should always display in the same
-window e.g after typing g on a breakpoint in the breakpoints buffer. Breakpoint
-icons are displayed both by setting a break with gud-break and by typing break
-in the GUD buffer.
-
-This works best (depending on the size of your monitor) using most of the
-screen.
-
-Displayed expressions appear in separate frames. Arrays may be displayed
-as slices and visualised using the graph program from plotutils if installed.
-Pointers in structures may be followed in a tree-like fashion.
-
-The following interactive lisp functions help control operation :
-
-`gdb-many-windows' - Toggle the number of windows gdb uses.
-`gdb-restore-windows' - To restore the window layout."
