http://bugs.debian.org/651538
[ Jordi Mallach ]
* Fix syntax errors in DEP5 copyright file (lintian).
* Use a versioned copyright Format specification field.
* Update Vcs-* URLs.
* Move transitional packages to the new metapackages section, and make
  them priority extra.
* Remove references to GNU/Linux and MESS sources from copyright.
* Add build variables for s390x.
* Use .xz tarballs as it cuts 4MB for the upstream sources.
* Add nplayers.ini as a patch. Update copyright file to add CC-BY-SA-3.0.

[ Emmanuel Kasper ]
* New upstream release. Closes: #651538.
* Add Free Desktop compliant png icons of various sizes taken from
  the hydroxygen iconset
* Mess is now built from a new source package, to avoid possible source
  incompatibilities between mame and the mess overlay.
* Mame-tools are not built from the mame source package anymore, but
  from the mess source package
