- Resurrect; unbreak on all supported versions of FreeBSD (and 8.X)

- Drop leading indefinite article from COMMENT text
- Stagify, convert to USES=libtool, switch to .tar.bz2 distfile

+Non-Uniform Rational B-Splines (NURBS) are parametric functions which can
+represent any type of curves or surfaces.  This C++ library hides the basic
+mathematics of NURBS, allowing the user to focus on the more challenging
+parts of their projects.
+
+The NURBS++ package includes a matrix library, an image manipulation
+library, a numerical library and a NURBS library.
