+
+Thanks to the crazy changes in V8 (and some in Node core), keeping native
+addons compiling happily across versions, particularly 0.10 to 0.12 to 4.0, is
+a minor nightmare.  The goal of this project is to store all logic necessary
+to develop native Node.js addons without having to inspect
+@code{NODE_MODULE_VERSION} and get yourself into a macro-tangle.
+
+This project also contains some helper utilities that make addon development a
+bit more pleasant.")
