This version is not compatible with older versions, so retain 2.48.15 by splitting into 2.4x and 2.5x subdirectories and using "@option is-branch". Initial diff has been looked at by kn@ (looks OK port- and build-wise on amd64) and giovanni@ (OK). Issues found by sthen@ (thanks!) and fixed by me. Take MAINTAINER (as discussed with giovanni@). OK sthen@
