I propose to rename the corresponding gzip-only scripts in the gzip

multi-compressor programs in zutils can replace them.

I have no objection to doing that, as a build-time option (for
backward compatibility).

I am not sure this is enough to guarantee the peaceful coexistence of both packages, unless the build-time option is to rename by default.

I mean, if a user installs zutils and then gzip, the gzip-only scripts would overwrite those of zutils. An unpleasant surprise!

Zutils is supposed to be an improvement over gzip-only scripts, therefore backward compatibility is supposed to be provided by zutils' programs themselves. (Zutils' zcat for example, ignores some gzip options to be compatible with gzip). What I think we have to find is a way to avoid one package overwriting files in the other.


Best regards,
Antonio.
