NOTE:

If you are upgrading WN from a version earlier than 1.17.6 you cannot
use your old mime.types file.  The format of this file has changed
to one which is more standard.  A fairly comprehensive mime.types file
(derived from the Debian Linux file) is included in /lib/mime.types.
I recommend you use it or modify it if you desire.  The correct format
is described in this file.
