I apologize for this OT mail but there were a number of requests some time ago for the English version of the Ochem manual for drawing chemical structures. I did not have it myself then, and the author was unavailable as well.
He just sent out a note about the latest distributon, and it now has a fully translated English manual. It can be found at http://www.2k-software.de/ingo/ochem.html I am beginning to work on updating my own Ochem macros and documentation as well. I'll gladly pass on the converter scripts I use with the package if anyone wants them. Kenward -- Small is the number of them that see with their own eyes and feel with their own hearts.
