Hey Dave,

Thanks for correcting me. I should read what I am writing before I hit the
send button :). It was a stupid mistake..

Appending path to PYTHONPATH will allow us to import the module in some
other Python script without requiring us to do sys.path.apend(). To execute
the script from bash what Dave suggests is correct.

Also, if you don't want to append path to PYTHONPATH you can also place the
module under site-packages directory under Python home directory.

Thanks,

- A
