[ANN] rpncalc-2.1 RPN Calculator for Python

[Raymond L. Buvel]

The rpncalc package adds an interactive Reverse Polish Notation (RPN)
interpreter to Python.  This interpreter allows the use of Python as
an RPN calculator.  You can easily switch between the RPN interpreter
and the standard Python interpreter.
