CLI usage

The current official and supported way to use Havok-N and EmojiHash from the CLI is to use the PHP implementation.

Usage:

php havokn.php <string|file> [depth] [iterations]

In English, that's php havokn.php, followed by either the string you want to hash or a path to the file you want to hash, optionally followed by the checksum depth, optionally followed by the number of hashing iterations.

php emojihash.php <string|file> [depth] [iterations] [emojilist file]

In English, that's php emojihash.php, followed by either the string you want to hash or a path to the file you want to hash, optionally followed by the checksum depth, optionally followed by the number of hashing iterations, optionally followed by a file containing a list of emoji to use.

If not explicitly specified, depth defaults to 8, iterations defaults to 0, and emojilist will try ./emojilist.txt, then ../emojilist.txt, and then fail if neither are found.

There is currently no way to pass an arbitrary hash to emojihash.php from the command line, but if that's really what you want, I'm sure you could hack it in there.
