Details:
It would be desirable to know the real filetype of a downloading file as soon
as possible. The filetype given by libmagic can then be compared with the file
extension. If they differ, say a "rar" is reaaly an "avi", the file is
probably a fake.
Libmagic, which is used in the unix "file" command can be used for this.
There didnt seem to be any mainatined libmagic wrappers for ocaml, so I tried
generating them with swig. It worked fairly well.
See attached file with the experiment.
This should of course be a configure-time option.
