You'll have to see with whoever made/maintain the package for your distro.

With Debian for example it looks like it's this guy: https://qa.debian.org/developer.php?email=satta%40debian.org

I think the command may be 'mp64'

(and don't feel bad for not realizing it - I can never remember this. I even have a 'maskprocessor' alias set up that does this:)

$ maskprocessor
You mean mp64
