Don't hesitate to ask me questions if our syntax is strange for you.

Good idea.

Hachoir goal is not to extract meta-datas. It's just one possible use of the
library. Main idea is to parse binary file into nice human reprensentation
(build a tree of field where each field is a Python object). Because I wrote
many parser to help Hachoir development, I just see that it would be cool to
extract meta-datas. And after that, a friend told me that libextractor
exists. That's why I'm writting to you :-)
