I'm developing it in PLT Scheme, so I'll use pipes than, will that
decision make it impossible to pass texmacs trees?

Nice, What I couldn't find was where is the specs for texmacs trees.
What's their syntax? I think I'll check the plugins code directly to see
if I find anything about that.

I don't have much time on my hands now since I'm about to deliver a MSc
report but I'll check it out afterwards. I can maybe give him a hand. Do
you have his contact?

I really read the whole section, however, not carefully. From what I
recall, there's not much about the scheme format but I'll check it out
again.

So, he wrote it all in Lisp!
