From c1ed362facbab3d08b5576950d4c6a68cfae9e75 Mon Sep 17 00:00:00 2001
From: Igor Gnatenko <ignatenko@redhat.com>
Date: Sat, 25 Feb 2017 12:28:16 +0100
Subject: [PATCH] add support for rich dependencies from dependency generators
Mostly achieved by replacing custom parser with the parseRCPOT().
Closes: https://github.com/rpm-software-management/rpm/issues/167
Signed-off-by: Igor Gnatenko <ignatenko@redhat.com>
(cherry picked from commit 8f509d669b9ae79c86dd510c5a4bc5109f60d733)
