# Setup i18N

# Calling `gettext.install()` injects `_()` in the builtins namespace and
# thus it becomes available globally (i.e. in the same process). Any python
# code that needs to use _() should make sure that it firsts imports this
# library.
#
# Note: we need to do this at the beginning of this module in order to
# ensure that the injection happens before anything else gets imported.
