NAME
       entropy - compute Shannon entropy of input

SYNOPSIS
       entropy <text>

DESCRIPTION
       entropy computes the Shannon entropy of the input string
       in bits per symbol. Higher entropy indicates more
       randomness or information content.

       Also reports: input length, number of unique symbols,
       and the theoretical maximum entropy for the observed
       alphabet size.

EXAMPLES
       $ entropy aaaa
       Shannon entropy: 0.0000 bits/symbol

       $ entropy abcd
       Shannon entropy: 2.0000 bits/symbol
