Your cshrc file should define $TEACH_DEMO and add the bin
directory to $PATH. For example, I have installed the file
in /usr/local/teach/ so my .cshrc file has the lines:

setenv TEACH_DEMO /usr/local/teach/
setenv PATH $TEACH_DEMO/bin:$PATH

The demonstrations can then be run by typing following the 
instructions on the web pages:

http://www.ch.cam.ac.uk/SGTL/teach/kinetics2.html

The demonstrations will only run if Gnuplot is installed
on the computer:
