reorders lines in a file in semirandom ways
This program reorders the lines in its input with no regard to the actual contents. Two permutation algorithms are available: randomization based on a good PRNG (the Mersenne Twister algorithm) and "shuffling", which permutes the lines in such a way that they're spread more or less evenly in the output. This mode is primarily intended for music playlists.
