;;; 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:

;;;###autoload
(define-minor-mode t-mouse-mode
  "Toggle t-mouse mode to use the mouse in Linux consoles.
With prefix arg, turn t-mouse mode on iff arg is positive.

This allows the use of the mouse when operating on a Linux console, in the
same way as you can use the mouse under X11.
It requires the `mev' program, part of the `gpm' utilities."
  :global t :group 'mouse
