+  Julia is a high-level, high-performance dynamic programming language for
+  technical computing, with syntax that is familiar to users of other
+  technical computing environments. It provides a sophisticated
+  compiler, distributed parallel execution, numerical accuracy, and an
+  extensive mathematical function library. The library, mostly written
+  in Julia itself, also integrates mature, best-of-breed C and Fortran
+  libraries for linear algebra, random number generation, FFTs, and
+  string processing. Julia programs are organized around defining
+  functions, and overloading them for different combinations of
+  argument types (which can also be user-defined).
