+[Date: Tue, 9 Jan 2001 20:52:51 -0500] [ftpmaster: James Troup]
+Removed the following packages from unstable:

+ROM; moved to non-US (now depends on libssl)

+=========================================================================

+Note that a removal batch may have many packages removed (unlike the one
+above, where only dsniff is removed).
+
+This script when ran as a standalone script will not connect to the database
+but will instead run a basic sanity test (to make sure that the input file
+hasn't changed in a way that would break the script).
