1. Allows you to attach to an already running Emacs gnuserv allows you to attach to an already running Emacs. This allows external programs to make use of Emacs' editing capabilities. It is like GNU Emacs' emacsserver/server.el, but has many more features. You do not need this package if you use XEmacs; it already includes gnuserv and gnuclient. If you want to use gnuserv with both GNU Emacs and XEmacs, you will only be able to use the alternative /usr/bin/gnuclient with one flavor of emacs; you will have to use either gnuclient.xemacs or gnuclient.emacs for the other flavor.
