commit 458df9f37492fdc8095dc2e37e232c292c91eecd Author: Olaf Hering <olaf@xxxxxxxxx> AuthorDate: Wed Jul 26 16:39:49 2017 +0200 Commit: Wei Liu <wei.liu2@xxxxxxxxxx> CommitDate: Fri Jul 28 17:49:43 2017 +0100 docs: add pod variant of xl-network-configuration.5 Convert source for xl-network-configuration.5 from markdown to pod. This removes the buildtime requirement for pandoc, and subsequently the need for ghc, in the chain for BuildRequires of xen.rpm.
