	 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 extentions 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.
