Debugging stand-alone JS apps

Hello,

There are several Eclipse JS debuggers around (e.g. in the Eclipse ATF
project) which use the jsdIDebuggerService interface, but they all
require XPCOM and run the debugger inside the Mozilla framework.

Since Spidermonkey is able to run without the Mozilla framework too, I
was wondering if it would be feasible to debug a JS application that
runs from a simple Linux shell?

Best regards,
Harald
