It was a historical mistake: originally we were going to use pkg_pretend for this. But claims were made that this would break some mythical auto-building systems, and that something machine-readable was needed. Unfortunately the Council bought this, and put through REQUIRED_USE without a reference implementation. Needless to say, the end result is something that isn't human-readable, and isn't used by any mythical auto-building systems. (Incidentally, Exherbo has a both human- and machine-readable implementation, which *is* used by an auto-building system, but the syntax won't meet Gentoo approval...) --=20 Ciaran McCreesh --Sig_/azoo8j4xzjPXJTZHqZTNoZ2 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlPSu5cACgkQ96zL6DUtXhFWXQCfRYDvRd47AeOLPaKZ1G7Oq+5t d+8An0cuKexMtT+HJn3loorOw2Q9DUYD =zDbF -----END PGP SIGNATURE----- --Sig_/azoo8j4xzjPXJTZHqZTNoZ2--
