+ (description
+ "The fast-histogram mini-package aims to provide simple and fast
+histogram functions for regular bins that don't compromise on performance. It
+doesn't do anything complicated - it just implements a simple histogram
+algorithm in C and keeps it simple. The aim is to have functions that are fast
+but also robust and reliable. The result is a 1D histogram function here that
+is 7-15x faster than @code{numpy.histogram}, and a 2D histogram function that
+is 20-25x faster than @code{numpy.histogram2d}.")
