+ "This is a library for quaternions. It contains most of the quaternion
+operations one would usually expect out of such a library and offers them both
+in non-modifying and modifying versions where applicable. It also tries to be
+efficient where plausible. Each quaternion is made up of @code{float}s, which by
+default are @code{single-float}s, as they do not require value boxing on most
+modern systems and compilers.")
