'''
The elib.intl module provides enhanced internationalization (I18N) services foryour Python modules and applications.
elib.intl wraps Python's :func:`gettext` functionality and adds the following onMicrosoft Windows systems:
- automatic detection of the current screen language (not necessarily the same as the installation language) provided by MUI packs, - makes sure internationalized C libraries which internally invoke gettext() or dcgettext() can properly locate their message catalogs. This fixes a known limitation in gettext's Windows support when using eg. gtk.builder or gtk.glade.
See http://www.gnu.org/software/gettext/FAQ.html#windows_setenv for moreinformation.
The elib.intl module defines the following functions:'''
__all__ = ['install', 'install_module']__version__ = '0.0.3'__docformat__ = 'restructuredtext'
import osimport sysimport localeimport gettext
from logging import getLogger
logger = getLogger('elib.intl')
def _isofromlcid(lcid): '''

This function ensures that changes to an environment variable are applied to each copy of the environment variables used by a process. Starting from Python 2.4, os.environ changes only apply to the copy Python keeps (os.environ) and are no longer automatically applied to the other copies for the process.
On Microsoft Windows, each process has multiple copies of the environment variables, one managed by the OS and one managed by the C library. We also need to take care of the fact that the C library used by Python is not necessarily the same as the C library used by pygtk and friends. This because the latest releases of pygtk and friends are built with mingw32 and are thus linked against msvcrt.dll. The official gtk+ binaries have always been built in this way. '''

Note that this is only one way, albeit the most convenient way, to make the _() function available to your application.
