Lack of examples make introduction to hachoir hard.
I have spent the last hour possibly two trying to find out how to use hachoir. The only example I can find is hackoir-metadata which is not very intuitive for someone who is not versed in writing hachoir code. I can not find any documention aside from the source either.
To tell the truth, since all I wanted to do was to extract the file name from torrent files I think it will be faster to start from scratch than to try and figure out how to do it using hachoir.
I think this is very sad since the package seem to be very usable for me and I assume for others, and I also hope that the error is all mine and I have just missed to look at an obvious place and there is plenty of documentation and examples out there.
