 // gt is a versatile calculator that supports both percentage calculations and
 // Reverse Polish Notation (RPN) expressions. It can be used in two modes:
 //
-// 1. Command-line mode: Pass calculations as arguments
-//    gt 20% of 150         # Calculate 20% of 150
-//    gt 3 4 +              # RPN expression: 3 + 4
