OK. Very good.

Several people on the jmol-users mailing list have asked about plotting
jcamp data and having it drive Jmol scripts.

Shravan and Richard from Ohio State University, USA are adapting a jcamp
applet so that it can send scripts to Jmol. I understand that the basis
for the applet came from Henry Rzepa. They plan to contribute it to Jmol.

I did not know that.

I have not yet seen the jcamp applet code, so I do not know if it is using
your parser.

Very good.
