+
+;;; 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."
