 Reverse Polish Notation Calculator
 ==================================
 
    The first example is that of a simple double-precision "reverse
 polish notation" calculator (a calculator using postfix operators).
 This example provides a good starting point, since operator precedence
 is not an issue.  The second example will illustrate how operator
 precedence is handled.
 
    The source code for this calculator is named `rpcalc.y'.  The `.y'
 extension is a convention used for Bison input files.
