Re: [gentoo-portage-dev] Few things, which imho would make portage better

[tvali]

Thank you much!

This is what i meant about searching :) Would it be now good to mix
this esearch code with emerge, then adding fields to db and making
emerge treebuilding fast, too? Or is there some utility to emerge,
which does all that?

Ühe eesti internetifirma lehel kohtasin tsitaati:
If you don't do it excellently, dont do it at all. Because if it's not
excellent, it won't be profitable or fun, and if you're not in
business for fun or profit, what the hell are you doing here?
