I did already have that catalogue present. Will check whether double or sth.

Description: Determines file type using "magic" numbers
File tests each argument in an attempt to classify it. There are three
sets of tests, performed in this order: filesystem tests, magic number
tests, and language tests. The first test that succeeds causes the
file type to be printed.
.
Starting with version 4, the file command is not much more than a wrapper
around the "magic" library.

So the N900 does have a description present at least. Peculiar that it would be missed then.
