+-- | PURPOSE  : Reports on all tablespaces including size and 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.          |
