=========================================

 and, please, no import inside functions (look at 'import rpm' in this grep 
 output  and many-many-many  import string/os/sys/etc  in other sources)...
 
 PythonStyleGuide (http://www.python.org/peps/pep-0008.html): 
 
   Imports
    - Imports are always put at the top of the file, just after any
      module comments and docstrings, and before module globals and
      constants.
