%description
The file command is "a file type guesser", that is, a command-line tool that
tells you in words what kind of data a file contains. Unlike most GUI systems,
command-line UNIX systems - with this program leading the charge - don't rely
on filename extensions to tell you the type of a file, but look at the file's
actual contents. This is, of course, more reliable, but requires a bit of I/O.
