Has anyone written a math editor which uses ASCII characters only?  I use TeX
for my own documents, of course, but we need something for use in e-mail and
USENET articles, something which will let us type

	  _                          _
	 /  +inf                 /  /  t                     \
	 |                   2   |  |                 2      |
	 |          1      -t /2 |  |          1    -u /2    |
	 |       ------ t e      |  |       ------ e      du | dt
	 |         ____          |  |         ____           |
	 |       \/2 pi          \  |       \/2 pi           /
	_/  -inf                   _/  -inf

and the like.

If no one else has done this, I'll consider doing it and distributing the
source free of charge.  (PLEASE do not flood my bulging mailbox with a million
"me too"s!)

By the way, mathematicians out there might be interested in evaluating that
integral.  The solution follows; if you don't want to peek yet, don't press
another key.


          ____
It's  1/(\/2 pi).  Rewrite it as a double integral, then change limits
and integrate with respect to  t  first.
