""" FIREUP: Plugin for the SALIS simulator.
File: fireup.py
Author: Paul Oliver
Email: paul.t.oliver.design@gmail.com
NOTE: REQUIRES TMUX TO WORK!
Use this script to run one (or several) previously saved simulations in the
background. Each simulator will run inside a tmux session.
Remember to give this file correct permissions (chmod +x). To use, call it
followed by an autosave interval (mandatory) and the list of save-files to
load. Save-file paths are always relative to the './bin/sims/' directory.
For example:
$ ./bin/plugins/fireup.py -a 0x100000 -f 20.01.sim 20.02.sim 20.03.sim
