fuzzylite (5.1+dfsg-1) unstable; urgency=medium
* new upstream version (Closes: #777858)
* removed debian/patches/20140705-minor-improvements-on-building-script as
upstream integrated it. Adjust build options in d/rules accordingly.
* delete debian/patches/20140714-building-from-objects-just-once and
debian/patches/20141027-fix-some-spelling as they have been applied
upstream
* install usr/lib/*/pkgconfig/fuzzylite.pc in fuzzylite-dev
* SONAME bump from 5.0 to 5.1, so renaming libfuzzylite5.0 to
libfuzzylite5.1
* add debian/patches/pkgconfig_installdir to install pkgconfig file in
correct location
