Assuming you have changed to /usr/local, please copy
aolserver/nsd.tcl.sample to aolserver/nsd.tcl and season to
taste.  An example server is in at aolserver/servers/server1, and
you should similarly copy the contents of this directory to, e.g.,
aolserver/servers/www.mydomain.com before modifying them.  

These files are examples only and will be deleted if you remove this
port.
