This archive is a self-contained tarball for building rump kernels,
including the build scripts and NetBSD kernel driver sources. The
archive is meant for example for networkless environments where
fetching the NetBSD kernel drivers at build-time is not possible.
You can recreate this archive by cloning the buildrump.sh repository [1],
checking out revision ${_revision}
and running the "tarup.sh" script.
To build rump kernels for the current platform, run "./buildrump.sh".
For crosscompilation and other instructions, see the git repository.
Unless you have a need to use this self-contained archive, it is
recommended that you use the git repository.
[1] https://github.com/rumpkernel/buildrump.sh
The following NetBSD source timestamps were used in this snapshot:
EOF

echo ">> Removing temporary files"
rm -rf "${DEST}" "${tarball}"
echo ">> Your archives are at ${tarball}.{gz,xz}"
