+     useless, -- This is a simple calculator script
+
+SYNOPSIS
+     useless, [add sub mul div] number1 number2
+
+DESCRIPTION
+     Use the useless, macro to make simple calulations like addition,subtraction,
+     multiplication and division.
+
+Examples
+     ./useless add 1 2
+       This will add 1 and 2 and return 3
+
+     ./useless mul 2 3
+       This will return 6 as a product of 2 and 3
+
+     ./useless div 6 3
+       This will return 2 as a quotient of 6 and 3
+
+     ./useless sub 6 5
+       This will return 1 as a remainder of substraction of 5 from 6
