+=========================================================================
+1. Introduction
+=========================================================================
+libLBFGS is a C port of the implementation of Limited-memory
+Broyden-Fletcher-Goldfarb-Shanno (L-BFGS) method written by Jorge Nocedal.
+The original FORTRAN source code is available at:
+http://www.ece.northwestern.edu/~nocedal/lbfgs.html
+
+The L-BFGS method solves the unconstrainted minimization problem:
+    minimize F(x), x = (x1, x2, ..., xN),
+only if the objective function F(x) and its gradient G(x) are computable.
+
+Refer to the libLBFGS web site for more information.

+2. How to build the sample program
+=========================================================================
+[Microsoft Visual Studio 2005]
+Open the solution file "test/lbfgs.sln" and build it.
+
+[GCC]
+$ cd test
+$ ./build.sh
