Locale directory
Python gettext looks for binary mo files for the given domain using the path
<localedir>/<language>/LC_MESSAGES/<domain>.mo. The default locale directory varies on distributions,
and it is /usr/share/locale in most cases.
If you store message catalogs in a different location, you need to specify the location via an environment
variable named <DOMAIN>_LOCALEDIR where <DOMAIN> is an upper-case domain name with replacing _ and . with -.
For example, NEUTRON_LOCALEDIR for a domain neutron and OSLO_I18N_LOCALEDIR for a domain oslo_i18n.
