Well, I'm sure you'll find a pybindgen limitation sooner or later :-) As you would with any other tool... But I have developed pybindgen mostly oriented to the features I needed to bind NS-3[1]. Regarding documentation, you are right. I would never condemn anyone for not using pybindgen due to lack of documentation, but I'm afraid I don't have time or predisposition for writing good documentation. The little tutorial documentation there is not even written by me, Mathieu Lacage wrote it (or most of it). Otherwise, pybindgen can still be useful for programmers with enough patience to work with incomplete documentation, and that's why I make it available anyway. If you find it useful, good for you, if not, I understand.
