At least fencepost.gnu.org doesn't have 7z, but does have p7zip, which is a shell script. That shell script invokes another shell script, called 7zr, which in turn invokes a program /usr/lib/p7zip/7zr. > - 7zr - a standalone minimal version that only handles 7z archives. > > - p7zip - a gzip like wrapper around 7zr.
