-define Package/file/description
- 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.
