L-BFGS-B, version 3.0 (April 25, 2011)
======================================

This program incorporates L-BFGS-B, the bound-constrained limited-memory
BFGS code of Ciyou Zhu, Richard H. Byrd, Jorge Nocedal, and Jose Luis Morales.
The authors released L-BFGS-B under the New BSD License (also called the
"Modified BSD License" or "3-clause license"). The version-3.0 source ships a
License.txt that states only that the code is released under the New BSD
