I read an article some time ago that stated that the original
2-3 developers wrote the tool in Lisp on a Symbolics machine
(back on the East coast I think).  Then when they decided to
make a product out of it, they wanted a fast, small, and portable
tool - so they recoded (redesigned?) it in C.  
I am still
searchin for the reference where I read that - but have not
found it yet.  Also, whenever I look at a Nexpert .kb file,
it really reminds me of the Lisp syntax that I am familiar with
- but then again there are probably only so many ways one
can write rules and object files...
