Not much, I guess. It's basically writing some scripts that will take the code base of some of the available high quality pascal projects, and then depending on what is available extract/merge documentation available as PDF, PasDoc, RTF, .HLP or method/function source code comments.

I would assume that one of my devs could write the needed scripts in three weeks or so.

So, basically a budget of <$5000.

For me - due to missing competence - the actual challenge would be to get a sample on how training data should optimally look like (for example the Python training set), and someone doing the actual training. For a newbie to get up the required level of competence surely will take more than three weeks.
