  Core is Jane Street Capital's Ocaml standard library overlay.  It
  provides tail recursive versions of non tail recursive functions in
  the standard library, changes the signature of many of the standard
  modules, and adds new functionality.

  Core_extended adds new functionality, but is only code reviewed on an
  ad-hoc basis.
