And where is this documented? (It has a documentation for the format, so
I guess if that was supposed to be "writing" only, that was a canonical
place to state it).

Thanks for the warning and the compaitibility wrapper. But please also
advertise that a bit wider. Just a mail to debian-devel is hardly enough
when breaking an advertised interface.

xfm is one of them. Perhaps I will find the time to file a list of
whishlist bugs to extend libmagic so it can be used instead of parsing
the files itself.
