+     "CRDS is a package used for working with astronomical reference files for
+the HST and JWST telescopes.  CRDS is useful for performing various operations
+on reference files or reference file assignment rules.  CRDS is used to assign,
+check, and compare reference files and rules, and also to predict those datasets
+which should potentially be reprocessed due to changes in reference files or
+assignment rules.  CRDS has versioned rules which define the assignment of
+references for each type and instrument configuration.  CRDS has web sites
+corresponding to each project (http://hst-crds.stsci.edu or
+https://jwst-crds.stsci.edu/) which record information about reference files and
+provide related services.")
