+"""runpy.py - locating and running Python code using the module namespace
+
+Provides support for locating and running Python scripts using the Python
+module namespace instead of the native filesystem.
+
+This allows Python code to play nicely with non-filesystem based PEP 302
+importers when locating support scripts as well as when importing modules.
