+%description
+bcal (Byte CALculator) is a command-line utility for storage conversions 
+and calculations. Storage, hardware and firmware developers work 
+with numerical calculations regularly e.g., storage unit conversions, 
+address calculations etc. If you are one and can't calculate the hex address 
+offset for (512 - 16) MiB immediately, or the value when the 43rd bit of 
+a 64-bit address is set, bcal is for you
