def exec_file(file, global_variables):
    '''Executes the provided script as if it were the original script provided
    to python.exe. The functionality is similar to `runpy.run_path`, which was
    added in Python 2.7/3.2.

    The following values in `global_variables` will be set to the following
    values, if they are not already set::
        __name__ = '<run_path>'
        __file__ = file
        __package__ = __name__.rpartition('.')[0] # 2.6 and later
        __cached__ = None # 3.2 and later
        __loader__ = sys.modules['__main__'].__loader__ # 3.3 and later

    The `sys.modules` entry for ``__name__`` will be set to a new module, and
    ``sys.path[0]`` will be changed to the value of `file` without the filename.
    Both values are restored when this function exits.
