+     "This package allows you to create and print scrambled environments for purposes
+such as randomized hint environments.  You can mark a location with a series of
+hints, and then print the hints at the end in a pseudo-random order.  The
+general structure follows: there is an outer environment which creates the
+label, an inner environment that creates the references, and a print command
+that prints out all of the hints.  This generalizes beyond hints; one can create
+scrambled solutions as well, etc.")
