Cmp

Cmp is a compression script for the Audrey. It was not part of Kojak but was designed to take advantage of the compressed file system used by the Audrey. It is installed as part of the Plus pack. You can also copy the script below to /nto/bin/cmp without installing any other executables except for cut. Cmp makes use of flashlzo which is part of kojak.
