+      Blitz++ is a C++ class library for scientific computing which provides
+      performance on par with Fortran 77/90. It uses template techniques to
+      achieve high performance. Blitz++ provides dense arrays and vectors,
+      random number generators, and small vectors (useful for representing
+      multicomponent or vector fields).
