 NLopt is a free/open-source library for nonlinear optimization,
 providing a common interface for a number of different free optimization
 outines available online as well as original implementations of various
 other algorithms. Its features include:
 
   - Callable from C, C++, Fortran, Matlab or GNU Octave, Python,
     GNU Guile, Julia, GNU R, Lua, and OCaml.
   - A common interface for many different algorithms -- try a different
     algorithm just by changing one parameter.
   - Support for large-scale optimization (some algorithms scalable to
     millions of parameters and thousands of constraints).
   - Both global and local optimization algorithms.
   - Algorithms using function values only (derivative-free) and also
     algorithms exploiting user-supplied gradients.
   - Algorithms for unconstrained optimization, bound-constrained
     optimization, and general nonlinear inequality/equality constraints.
+  - Free/open-source software under the GNU LGPL
+    (and looser licenses for some portions of NLopt).
