Is this good enough?
Quoting the relevant section from that document ... So far, based upon both user feedback and our own experiences, we feel that ZCPR is a significant contribution to the Public Domain, and everyone who has used it greatly prefers it over standard CP/M. ZCPR is being released for Public Distribution through the SIG/M User's Group of the Amateur Computer Group of NJ. In the spirit of Public Domain software, ZCPR is by no means a panacea, but is IS a very nice stepping stone, and you are encouraged to feel free to modify it to please yourselves... I am not the person who decides this sort of thing for Debian, but that looks good to me. Cheers, Walter Landry
