+Eigen is primarily MPL2 licensed. See COPYING.MPL2 and these links:
+ http://www.mozilla.org/MPL/2.0/
+ http://www.mozilla.org/MPL/2.0/FAQ.html
+
+Some files contain third-party code under BSD or LGPL licenses, whence the other
+COPYING.* files here.
+
+If you want to guarantee that the Eigen code that you are #including is licensed
+under the MPL2 and possibly more permissive licenses (like BSD), #define this
+preprocessor symbol:
+ EIGEN_MPL2_ONLY
+For example, with most compilers, you could add this to your project CXXFLAGS:
+ -DEIGEN_MPL2_ONLY
+This will cause a compilation error to be generated if you #include any code that is
+LGPL licensed.
