reattatchabe slime

Here is a little makedef file to start/stop a lisp application and allow the developer to attach to the running process with attachtty or slime.

For a new application you create a new Makefile, define LISP_DIR and LISP_APP and then include this makedef file. You can then use the following targets with your application: start, stop, restart, attach, slime, dribble and log.

makedef

# -*- makefile -*-
### User needs to define the lisp working directory
#LISP_DIR=${HOME}/lisp/website
### ...and lisp application
#LISP_APP=server.lisp
