PENTOMINOES
Some Pentomino Utilities

PENTOMINOES is a C library which provides some utilities for manipulating pentominoes.

A pentomino is a shape formed by connecting 5 unit squares edgewise. Ignoring reflection and rotation, there are 12 distince pentominoes, nicknamed F, I, L, N, P, T, U, V, W, X, Y and Z.
