+  (description "@code{spin} is a simple interface for common development
+tasks.  It comes with a few common build commands out the box, but can
+easily be customized per project.
+
+The impetus behind developing the tool was the mass migration of scientific
+Python libraries (SciPy, scikit-image, and NumPy, etc.) to Meson, after
+distutils was deprecated.  When many of the build and installation commands
+changed, it made sense to abstract away the nuisance of having to re-learn
+them.")
