Tags: 3.2.0~rc1-1
[Alberto Luaces]
* New upstream release.
* Updated standards version (3.9.4).
* Updated SVN URL.
* Removed the static version of the libraries since they impose a huge
  load on the build servers, add additional complexity on the build
  scripts, and make a great impact on the size of the packages, given
  the very small cases where they are useful.
* Acknowledge NMU.

[ Manuel A. Fernandez Montecelo ]
* Switch to @debian.org address
