### Commentary:

## This file is obsolete.  Use emacsclient -a instead.

## This defines a bash command named `edit' which contacts/resumes an
## existing emacs or starts a new one if none exists.

## One way or another, any arguments are passed to emacs to specify files
## (provided you have loaded `resume.el').

## This function assumes the emacs program is named `emacs' and is somewhere
## in your load path.  If either of these is not true, the most portable
## (and convenient) thing to do is to make an alias called emacs which
## refers to the real program, e.g.
##
##        alias emacs=/usr/local/bin/gemacs
