That sounds ambitious, but you're welcome to try!

If you say so ;-)

The recently added jscript stubs are probably a decent place to start.
 Getting yourself familiar with COM is probably important to the
success of your project.  I'd recommend a copy of Don Box's Essential
Com as the best way to "get" COM in a hurry.  There are plenty of
online references too, of course.

One general point is that people often don't plan for the amount of
time needed to get patches accepted--it's often more than people
realize.  You might start by trying to get a stub DLL for vbscript
accepted, just to get the hang of the development process.  Check out
the git tree, build it, make some changes, commit to it, and send the
patches in.  You'll find instructions on how to do all that on the

Looking forward to seeing your application.  Good luck,
