for name in glob.glob(src + '/dicos/*.xml'):
    dico = name.split('/')[-1]
    dico_name = dico
    with open(name) as dicoxml:
        b64dico = base64.b64encode(dicoxml.read())
        ret = zephir.dicos.add_dict(11, dico_name, b64dico)
        print dico_name,id_variante, ret
        ret = zephir.dicos.add_variante(id_variante, 'local', dico_name)
        print ret
    dico_files = {}
