 DESCRIPTION
 ===========
 
-**cython_freeze.py** generates a C source file to embed a Python interpreter
+**cython_freeze** generates a C source file to embed a Python interpreter
 with one or more Cython modules built in.  This allows one to create a single
 executable from Cython code, without having to have separate shared objects
 for each Cython module.
