### Commentary:
|
|
|
|
## 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
|
|
|

|
|
# Do not just test if these files are sockets. On some systems
|
|
# ordinary files or fifos are used instead. Just see if they exist.
