+    Binder is a tool for automatic generation of Python bindings
+    for C++11 projects using Pybind11 and Clang LibTooling libraries.
+    That is, Binder, takes a C++ project and compiles it into objects
+    and functions that are all usable within Python.
+    Binder is different from prior tools in that it handles special
+    features new in C++11.
