config ADK_PACKAGE_FILE prompt "file.............................. a file type guesser" tristate default n help 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. http://www.darwinsys.com/file/
