CAMEO (Computer Assisted Mechanistic Evaluation of Organic reactions) is a modular expert system, a computer program that predict the products of organic reactions given starting materials, reagents, and conditions. Although CAMEO has been mainly developed for the VAX/VMS system originally, our recent efforts made it also available on Macintosh and X11/Motif.
Detailed description of X11/Motif version of CAMEO is available from web page: http://zarbi.chem.yale.edu/products/cameo/ or http://chemnews.cambridgesoft.com/art.cfm?S=160.
