+     "This package provides a a simple program to predict the levels of
+background emission in JWST observations, for use in proposal planning.
+
+It accesses a precompiled background cache prepared by Space Telescope Science
+Institute.  The background cache is hosted by the Mikulski Archive for Space
+Telescopes (MAST), so you need internet access to run the tool with the remote
+cache.  It is possible to download the full background cache to your local
+machine.")
