We have made various changes to the duende executable and these need to
be reflected in the Debian man page.

-For example, suppose one invokes duende thusly:
-
-.nf
- duende /usr/local/sbin/maradns
-.fi
-
-If invoked thusly, duende will log all messages with the "ident"
-(program
-name) of "/usr/local/sbin/maradns". If this is not desired, invoke
-duende
-with something like:
-
-.nf
- export PATH=$PATH:/usr/local/sbin
- duende maradns
-.fi
-
-This will log messages with a (more sensible) "ident" of maradns.

-Note: If a non-POSIX Bourne shell (such as csh, es, rc, or fish) is
