+-- | PURPOSE  : Reports on all data file usage. This script was designed to     |
+-- |            work with Oracle7 and Oracle8. This script can be run against   |
+-- |            higher database versions (i.e. Oracle8i) but will not return    |
+-- |            information about true TEMPORARY tablespaces. (i.e. use of      |
+-- |            "tempfiles")                                                    |
+-- | NOTE     : As with any code, ensure to test this script in a development   |
+-- |            environment before attempting to run it in production.          |
