Package generated.

Put build-time configuration files in src/build/<package>/<upstream-ver>, e.g.:
    src/build/linux-libre/3.10.45~gnu/config

Put run-time configuration files in src/run/<package>, e.g.:
    src/run/lilo/etc/lilo.conf.in

Then run ppt-mkpkgs to generate metadata files for binary packages.
