Drone is a tool for automatically running batch jobs of a simulation program. It allows sweeps over arbitrary sets of parameters, as well as multiple runs for each parameter set, with a separate random seed for each run. The runs may be executed either on a single computer or over the Internet on a set of remote hosts. Drone is written in Expect [4] (an extension to the Tcl [6, 10] scripting language) and runs under Unix. It was originally designed for use with the Swarm agent-based simulation framework [5], but Drone can be used with any simulation program that reads parameters from the command line or from an input file. This document describes how to install and use Drone.
