During command line operation, remove the following error when using Python 2.6 and 2.7:
"TypeError: 'encoding' is an invalid keyword argument for this function"
Use the 'io' module common to both Python versions to remove the 2.6 TypeError.
Python 3 operation is unchanged.
Also made a slight clarification to the command line usage text.
