        By default a deflate zip algorithm is used. To switch to
        the stored algorithm, `zip` can be set to ``'stored'``.

        `extensions` and `filter_func` are passed to :meth:`list_templates`.
        Each template returned will be compiled to the target folder or
        zipfile.

        By default template compilation errors are ignored.  In case a
        log function is provided, errors are logged.  If you want template
        syntax errors to abort the compilation you can set `ignore_errors`
        to `False` and you will get an exception on syntax errors.

        If `py_compile` is set to `True` .pyc files will be written to the
        target instead of standard .py files.  This flag does not do anything
        on pypy and Python 3 where pyc files are not picked up by itself and
        don't give much benefit.
