Re: JS engine(s) provided by gnustep

[H. Nikolaus Schaller]

SimpleWebKit had all WebView interfaces to call JS and itself contains some 
incomplete JS (ECMA-Script) interpreter.

There wasn't much activity (besides Riccardo) from the community to work on 
this framework and make it more useful and for example provide the 
JSVirtualMachine class.

Key question is if you want DOM integration (i.e. JS within a browser) or a 
stand-alone JSVirtualMachine class.
