+ "Run gdb on program FILE in buffer *gdb-FILE*.
+The directory containing FILE becomes the initial working directory
+and source-file directory for your debugger.
+
+If `gdb-many-windows' is set to t this works best in X (depending on the size
+of your monitor) using most of the screen. After a short delay 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
+\[mouse-2\] gdb-frames-select | SPC gdb-toggle-bp-this-line
+ | g gdb-goto-bp-this-line
+ | d gdb-delete-bp-this-line
+---------------------------------------------------------------------
+
+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.
+
+Displayed expressions appear in separate frames. Arrays may be displayed
+as slices and visualised using the graph program from plotutils if installed.
+
+If `gdb-many-windows' is set to nil then gdb starts with just two windows :
+the GUD and the source buffer.
+
+The following interactive lisp functions help control operation :
+
+`toggle-gdb-windows' - Toggle the number of windows gdb uses.
+`gdb-restore-windows' - to restore the layout if its lost.
+`gdb-quit' - to delete (most) of the buffers used by gdb."
