;;; Commentary:
|
||
|
||
;; This package provides access to mouse event as reported by the gpm-Linux
|
||
;; package. It tries to reproduce the functionality offered by Emacs under X.
|
||
;; The "gpm" server runs under Linux, so this package is rather
|
||
;; Linux-dependent.
|
||
|
||
;; The file, t-mouse.el was originally written by Alessandro Rubini and Ian T
|
||
;; Zimmerman, and Emacs communicated with gpm through a client program called
|
||
;; mev. Now the interface with gpm is directly through a Unix socket, so this
|
||
;; file is reduced to a single minor mode macro call.
|
||
|
||
;;
|
||
|
||
;;; Code:
|
||
|
||
;; Prevent warning when compiling in an Emacs without gpm support.
