NPI
===

NPI is an unpretentious calculator in RPN mode.

In the Twenties, Jan Lukasiewicz developed a system of formal logic making it
possible the mathematical expressions to be indicated without brackets while
placing the operators avant (notation of prefix) or after (notation of suffix)
the operands.  
The notation of suffix is named Polish notation reversed (RPN = Reverse
Polish Notation) in the honor of Lukasiewicz.

With this program you will be able to calculate maths expression in the Unix
shell using the RPN notation and with historic and completion support.
