* Removed patch system (not used): - removed instuctions in debian/rules; - removed quilt from Build-Depends in debian/control. * Re-enabled tests: - uncommented test command in debian/rules; - uncommented previously missing build-dependencies in debian/control. - Re-enabled tests and uncommented build-dependencies accordingly. * Removed libmodule-build-perl and libtest-harness-perl from Build-Depends-Indep (provided by perl-modules). * Better cleaning of empty directories using find -type d -empty -delete instead of rmdir in debian/rules (LP: #324001).
