Ok, I'll delay the feature in my software then. When (approximately of 
course) do you think this might happen?

Very interesting, thank you for the pointer! I understand much better 
now! When you'll release it, will you make a config table to configure 
the features enabled in the parbuilder?

I'm no ConTeXt user, but if I might help in any way, do not hesitate to 
sillicitate me!

Thank you very much for having done such a work already!

Yes, I think I'll wait for the official release of the Lua parbuilder.

Thank you very much!
