It's certainly an aid, at least the bottom part (like i'd said, I;d foound several different Gentoo docs giving me descriptions of what slots are, so I knew that, just that there seem to be no docs anywhere I can locate IN Gentoo that tell you HOW to use slots. So, now I know that the parens signal the slot info, but how do I choose them, select one over anther, adn even to search for them in emerge? You gave nice examples, but do you see why I so much dislike examples when they come INSTEAD OF the full syntax description? Cause then you only learn what the example wants to show, and people don't present exhaustive examples, because (reasonably enough) examples aren't meant to be exhaustive, that's what the syntax explanations are for. I just wish that a rule would be promulgated in Gentoo documentation that no one could be allowed to present an example unless they'd gotten out a syntax explanation first. It won't happen, but I wish it would. > :-) :-) -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFH3BD9z62J6PPcoOkRAjigAJ0SaEtU28251Y0HG/HElyFkXg8p+QCbBEKs u097YBqaJKrRZ5IpMzy4iP4= =wK98 -----END PGP SIGNATURE----- -- gentoo-user@lists.gentoo.org mailing list
