Hi friends,
Pat, I once used this library to help me with some unknown files:
https://bitbucket.org/leafstorm/lua-mimetypes
Hope it could give us some pointers and ideas. :)
Cheerio!

Hello
In practice, identifying all image files formats (tiff, png, pdf...) *should*
work with the first 4 bytes of the file (they were designed this way).
I think I'll go that way, but I still wish (feature request) that LuaTeX does not fail
with a fatal error if an unknown file format is encountered, instead it would be nice to
have something like "return nil, errormessage".
Thanks
Patrick
