Note
This package is a namespace package. You can extend the langdev package in separated filesystem path. In order to do that, creates a folder named langdev. Then, save the langdev/__init__.py file of the following content:
''':mod:`langdev` --- LangDev
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
'''
from pkgutil import extend_path
__path__ = extend_path(__path__, __name__)
Note that you must not make any variables/functions/class in the package, and creates modules like langdev.foobar under the package instead.
