Name of the software
Why we should include this into the repository, i.e. what does it do that the alternatives do not?
backward compatibility, some shell scripts are written using this utility
Is it open source?
If it is open source, please provide a link to the most up to date, versioned source tarball/zipfile. master.zip links will not be accepted.
If there are no upstream releases but the inclusion policy is otherwise met, please provide a link to the source repository (i.e. GitHub)
As requested, this is ineligible for inclusion. The mircpio upstream also contains alternatives for the tar and cpio commands. If it were to be included, I have zero doubt that people will get repeatedly annoyed that only pax is enabled and integrating it correctly to allow it to be a replacement for tar is out of scope. I'd also like to point out that Solus does not strive for strict POSIX compliance. If we did, GNU Coreutils and glibc would would be ineligible for inclusion.
