+"""
+The temp module provides a NamedTemporaryFile that can be re-opened on any
+platform. Most platforms use the standard Python tempfile.TemporaryFile class,
+but MS Windows users are given a custom class.
+
+This is needed because in Windows NT, the default implementation of
+NamedTemporaryFile uses the O_TEMPORARY flag, and thus cannot be reopened [1].
