description:
    Fast solver for exact set cover problems
    (<http://en.wikipedia.org/wiki/Exact_cover>) using Algorithm X as described in
    the paper /Dancing Links/, by Donald Knuth, in
    /Millennial Perspectives in Computer Science/, P159, 2000
    (<https://arxiv.org/abs/cs/0011047>).
    .
    To get started, see the documentation for the "Math.ExactCover" module below.
    .
    Build examples with @cabal install -fbuildExamples@ or @stack build --flag
    exact-cover:buildExamples@. Examples include a Sudoku solver.
