+Developers need to memorize a whole bunch of magic command-line incantations.
+These incantations may also change over time. Often, Makefiles are used to
+provide aliases, but Makefiles can be convoluted, are not written in Python,
+and are hard to extend. The goal of spin is therefore to provide a simple,
+user-friendly, extendable interface for common development tasks. It comes with
+a few common build commands out the box, but can easily be customized per
+project.
