This program will take a file, input stream, or list of 'words' and repeat
them in a random order to the given output file or stdout. Kinda the opposite
of sort...

rand [-lwvh] [-f <input file>] [-o <output file>]

Pipe usage:
	/bin/ls | rand [-lw] [-o <output file>]
file usage:
	rand [-lw] -f COPYING [-o <output file>]
other:
	rand [-vh]


Installation: read INSTALL.

Bug reports:
	email [email protected], provide as much useful info as possible.

What to do with this? well, you can queue up programs in a random order... someone was complaining about mpg123 not having a 'shuffle' command (which it does), this could provide that. A teacher writing a test could use this to generate tests that have the same questions but in different order... etc etc etc. One interesting use was a sysadmin using this to scramble 'script kiddies' exploit sources. While not completely ethical, it's terribly amusing :)


Thanks to Dr Shade <[email protected]> (Southwest Missouri State University)
for redoing the randomizing algorithm to be lightening fast. O(n^2) to O(n).

Thanks to Martin Hinsch for proposing the time() seed

Thanks to buccaneer and MLongHair for helping me get it working on
