Lets one import grampslocale directly in a test script:
>>> from gramps.gen.utils.grampslocale import GrampsLocale
>>> import os
>>> gl = GrampsLocale(lang='fr_FR.UTF-8', localedir=os.path.join('build', 'mo'))
>>> tr = gl.get_translation().gettext
>>> tr("List of known family trees in your database path\n")
u'Liste des arbres familiaux connus dans votre chemin de base de donn\xe9es\n'
