A program and language for the numerical study of deterministic and
stochastic dynamical systems, which may evolve in continuous or
discrete time. It loads the definition of a dynamical system in an
equation oriented language, translates this into C++, compiles and
links this, and solves the equations numerically with the speed of a
compiled (rather than interpreted) program. It has a GUI that allows
the program to be controlled and the parameters changed easily.

Available at ftp.uu.net/pub/math/gnans/.  As of 2002-04-25, binaries
for Irix, Solaris, and GNU/Linux were available at that location.
ftp.mathematik.uni-bremen.de, supposedly the source of this mirror,
doesn't seem to exist and ftp.math.uni-bremen.de doesn't have it.
