This program is written entirely in 680x0 assembler, for
    optimal speed. With the LhA interface, it is now the fastest
    disk compressor for Amiga.
    By adding several useful commands, like the MFM reading,
    and other commands, the OWS is the most flexible disk packer out
    for amiga. The OWS also works with High density disks, which is
    a brand new AmigaDOS standard for Amiga.
