Here we give information about the platforms on which the package runs, and how to obtain a copy. In its default form the package works only in demonstration mode, but the demonstration version can be switched to full functionality by a licence key which can be obtained from the developers.
Licence keys are free to academic sites but profit making sites are required to pay.
Commercial sites wishing to switch from the demonstration mode and try the full functionality of the package can obtain a free time limited licence. This directory contains demo versions of the package which can be switched to full use by a licence key. Please report any ftp problems. If it appears necessary we could consider providing more sites from which to download the package. For those who require a copy on CD, postage is also free.
