SimPack is a collection of C tools (routines and programs) for computer simulation. The purpose of SimPack is to provide people with a ``starting point" for simulating a system. The intention is that people will view what exists as a template (or ``seed") and then ``grow a simulation program." SimPack tools have been used for six years of teaching computer simulation at the undergraduate (senior) and graduate levels at the University of Florida. You can subscribe to the SimPack mailing list by sending mail to majordomo@cis.ufl.edu with the message: subscribe simpack. A message containing the first word help will provide you with all the commands available through the list server.
