 The neural network simulator I have used most is called XERION and is
 available free-of-charge:
 (a) You can get the source from the anon. FTP site:  ai.toronto.edu
 Look in pub/xerion.
 (b)  There is a mailing list for people using xerion.  See the README
 file for more information.
 (c) Questions, comments and bugs should be sent to xerion # - at - #
 ai.toronto.edu
 (d) Here is some additional information on XERION:
 Xerion is a Neural Network simulator developed and used by the
 connectionist group at the University of Toronto. This release
 (Version 3.1) contains libraries of routines for building networks,
 and graphically displaying them.  As well it contains an optimization
 package which can train nets using several different methods including
 conjugate gradient. It is written in C and uses the X window system to
 do the graphics. It is being given away free of charge to Canadian
 industry and researchers (and anyone else who wants it). It comes with
 NO warranty.
 This distribution contains all the libraries used to build the
 simulators as well as several simulators built using them (Back
 Propagation, Recurrent Back Propagation, Boltzmann Machine, Mean Field
 Theory, Free Energy Manipulation, Kohonnen Net, Hard and Soft
 Competitive Learning). Also included are some sample networks built
 for the individual simulators.
 There are man pages for the simulators themselves and for many of the
 C language routines in the libraries. As well, xerion has online help
 available once the simulators are started. There is a tutorial on
 using Xerion in the 'doc' directory.
 Xerion has been run and (pretty well) tested on the following
 platforms:
 SGI Personal Iris and SGI 4d running IRIX 4.0.1
 Sun 4 running SunOS 4.1.2
 Sun 3 running SunOS 4.0.3
 It has been compiled and *minimally* tested on the following platforms:
 DEC 5000 running ULTRIX
 DEC Alpha running OSF/1
 HP 730 running HP-UX 8.07	 (Thanks to Joe Devlin at USC).
 It has been tested with MIT X11R4 and X11R5 (libraries: Xaw, Xmu, Xt,
 X11).  Xerion will probably run on other machines with some
 modifications, but we haven't tested it on them and make no
 guarantees.
 Hope this helps.
 Cheers
