*************************************************************************
** This file contains a simple command-line utility for converting from
** integers and WhereCost values and back again and for doing simple
** arithmetic operations (multiple and add) on WhereCost values.
**
** Usage:
**
**      ./wherecosttest ARGS
**
** Arguments:
**
**    'x'    Multiple the top two elements of the stack
**    '+'    Add the top two elements of the stack
**    NUM    Convert NUM from integer to WhereCost and push onto the stack
**   ^NUM    Interpret NUM as a WhereCost and push onto stack.
**
** Examples:
**
** To convert 123 from WhereCost to integer:
** 
**         ./wherecosttest ^123
**
** To convert 123456 from integer to WhereCost:
**
**         ./wherecosttest 123456
