# Add the manually vendored tarball.
# 1) Create a tar archive optimized to reproduced by other users or devs.
# 2) Compress the archive using XZ limiting decompression memory for
#    pretty constraint systems.
# Use something like:
# tar cf $P-deps.tar go-mod \
#       --mtime="1970-01-01" --sort=name --owner=portage --group=portage
# xz -k -9eT0 --memlimit-decompress=256M $P-deps.tar
