From a03daad0734428ded0398c9d71582f90063f3493 Mon Sep 17 00:00:00 2001 From: Xavier Chantry Date: Tue, 12 Oct 2010 20:13:32 +0200 Subject: alpm: add new alpm_find_satisfier function whatprovides and splitdep were removed, so depcmp alone is quite useless now without splitdep, and deptest is not flexible enough. Introduce a new alpm_find_satisfier which is hopefully more flexible, this should make implementation of deptest very easy, and also help alpm tools such as pactree.
