+;; This file defines functions that support GNU Emacs using the Apollo
+;; Graphics Primitives (GPR).  See the file "APOLLO.README" for a description
+;; of the key bindings set up by this file.

+;; The following people have contributed ideas that have helped make this
+;; interface possible: Nathaniel Mishkin, Rob Stanzel, and Mark Weissman of
+;; Apollo Computer, Dave Holcomb of CAECO, Vincent Broman of NOSC, and J. W.
+;; Peterson of the University of Utah.
+
+;;; Change Log:
+;; Bob Weiner, Motorola, Inc., 2/2/89
+
+;; Added section to 'apollo-clean-help-file()' to remove underlining
+;;   and overstriking (only by the same letter) from Apollo '.hlp' files.
+;;   Based on the 'nuke-nroff-bs' function in man.el.
+;; Changed apollo-mouse-{cut,copy,paste} commands so that they work
+;;   with the DM paste buffer.  This combined with cut,copy,paste
+;;   bindings of the mouse keys allows quick and easy copying from
+;;   Emacs windows to DM windows.
+;; Added 'unbind-apollo-mouse-button' and 'unbind-apollo-function-key'
+;;   commands.
+;; Added 'apollo-mouse-cut-copy-paste' command which provides a
+;;   second set of mouse key functions that can be set with one key
+;;   press and cleared with another key press.  Put default mouse key
+;;   bindings into a command called 'apollo-mouse-defaults' so that
+;;   they can be used to clear any other mouse bindings.
+;; Both these commands affect the DM mouse key bindings as well.
+;; Added 'apollo-mouse-cancel-cut-copy-paste' command which resets the mouse
+;;   key defaults within Emacs and the DM.  The variable
+;;   '*dm-mouse-key-bindings-file*' should be set within an initialization
+;;   file to the pathname of file that executes a user's default DM mouse
+;;   key bindings.
+
+;; Bob Weiner, Motorola, Inc., 2/23/89
+
+;; Added ':' as valid character within a filename (if not at the end)
+;; in the command 'extract-file-name-around-point'.  For remote UNIX
+;; operations such as rcp and rsh commands which use the syntax,
+;; <host>:<path>.
+
+;; Bob Weiner, Motorola, Inc., 3/09/89
+;;
+;; Modified 'apollo-mouse-find-file' and 'apollo-find-file' so that they
+;; recognize buffer names in addition to directory or file paths.  A buffer
+;; name is recognized before a path name, if the match buffer names flag is
+;; enabled.  Added the command 'extract-buf-or-file-name-around-point' to
+; support this functionality.  Added find file in other window option to
+;; these two find-file commands.
+
+;; Bob Weiner, Motorola, Inc., 3/20/89
+
+;; Changed (funcall *apollo-key-bindings-hook*) to (run-hooks
+;; '*apollo-key-bindings-hook*) which is what it should be.
+
+;; Bob Weiner, Motorola, Inc., 4/20/89
+
+;; Rebound M2D button to perform different functions by buffer and location in
+;; buffer.  Executes 'smart-key-mouse' command found in smart-key.el.
+;; Meta-M2D executes 'smart-key-mouse-meta'.  M2U is unbound.
+
+;; Bob Weiner, Motorola, Inc., 8/1/89
+
+;; Fixed 'apollo-mouse-move-point' and 'apollo-mouse-move-mark' so they do
+;; not set the mark gratuitously.  They are bound to M1D and M1U respectively.
+
+;; Bob Weiner, Motorola, Inc., 4/11/90
+
+;; Bound left and right box arrow keys to scroll right and left,
+;; respectively, which most closely emulates their DM functions.
+
+;;; Code:
+
+(defvar *dm-mouse-key-bindings-file* "/sys/dm/std_keys3"
+  "Path of the DM key binding file which sets up a user's default mouse key
+bindings.  If none exists, this value should be set to one of the
+/sys/dm/std_key* files which set up DM key defaults.")
+
+;;; Set this variable in your ".emacs" to a function to call to set up
+;;; additional key bindings.
+;;;
+(defvar *apollo-key-bindings-hook* nil)
+
+;;; Set this variable non-NIL in your ".emacs" to enable preemption of normal
+;;; Display Manager bindings.
+;;;
+(defvar *preempt-display-manager-bindings* nil)

+;;; *paste-buffer-directory* to point to the paste buffers directory.

+;;; minibuffer area.
