Awesome.

Was this a project that can be seen publicly?

Very true.

I think that would be a terrific addition.

And if joined the project and contributed your code, we could very well
start by maintaining it in a branch, and progressively bring it back in
the trunk.

Does this integrates with the Groovy Eclipse plugin?
Note that based no the efforts of the Summer of Code's Anton and Wayne,
we now have better capabilities to write plugins in Groovy.
http://wiki.eclipse.org/Add_the_ability_to_write_plugins_using_jruby_or_
groovy.
That would be awesome if we could build on Anton's work at the same
time.

I look forward to it. To avoid putting too much load oon the list, what
about putting it either as aa bugzilla post attachment of a wiki post?
You could then send and email to the list for everyone to peek at it.

My best suggestion would be start a wiki page under
http://wiki.eclipse.org/VE/Documentation
We could use that as a base to later pull that into plugins as doc.
Cathy: you are a a god send!
welcome!
