* How can I update the po files, formerly I used "make update-po"? - You can call the build_i18n command with the -m (--merge-po) option: ./setup.py build_i18n -m * The domain and further intltool settings from the setup.cfg are not applied correctly. - Please make sure that there is no Makefile in your po directory. Intltool seems to prefer the values from there.
