Hi John,
Quite some time ago you send me this code of yours. It somehow
disappeared in my mail and only by now I tried it out, great, really
Only one question
I copied your code in a org file, executed the src sections and
obtained:

How do I suppose to continue now? Because if I export this to a latex
file the latex equations are not exported! I admit that I only use org
files this way export them to latex and continue working.
What do I miss?
Thanks
Uwe
