>Description:
On 15-Jul-2004, McAfee changed the format of the readme.txt in their DAT
file tarballs so that it no longer contains the version number of the
DAT files.  This action broke the update_dat script.
>How-To-Repeat:
Run the update_dat script.
>Fix:
Apply the following patch.

+# Modified by Jason White <jdwhite%jdwhite.org@localhost>  22-Jul-2004
+#   * Work around changes to McAfee DAT file distribution on 15-Jun-2004.
+#      - readme.txt no longer contains DAT file version, so we now
+#        use update.ini from server and pkgdesc.ini from tarball to 
+#        determine current and old DAT file version.
+#   * Updates fetched using faster, more reliable HTTP server.
