I was under the impression a copy of photot was available on the web -
I'm a bit confused now because checking my personal Maxima archive I
have a copy of photot.lisp and photot.mailer but Google finds neither.
Dr. Fateman, I thought I remembered this being on your website - I have
no other plausible source for where I got it - but I'm not spotting it now.

I see no license info, but there is a copyright notice from 1979 for the
Regents of the University of California so presumably they would have
final say in any licensing of the code.  On the other hand the author
indicates it's formatted more like C code than lisp code so perhaps a
re-factoring/re-write would be in order anyway...
