Re: [gentoo-soc] Rework Porthole to use the new public portage API -- Weekly report #4

[Brian Dolbec]

Detlev, I would continue implementing as much of the pkgcore backend as possible before creating replacements or missing functionality.  That will give ferringb a chance to move and possibly offer other ways of doing it.  In the meantime use portage for the missing func()'s.
