The link is as follows: http://www.mozilla.org/js/ under the "What
JavaScript Implementations are Available?" section which I excerpted as
follows:

"... This engine, code named SpiderMonkey, is implemented in C. The Rhino
engine, created primarily by Norris Boyd (also at Netscape) is a JavaScript
implementation in Java..."

Is this not correct?

Also, what's the difference bet. Spidermonkey and Seamonkey (I saw that name
while using the online doc. for JS_macros under Spidermonkey yet the links
and refs seemed pointed to "Seamonkey"???

The testcase I got was the jsshell included as part of the regular download
from Nombas (available to all for free). I looked into the source and it
seemed completely legitimate.
