                     11: .SH SYNOPSIS
                     12: /etc/resolv.conf
                     13: .SH DESCRIPTION
                     14: .LP
                     15: The resolver configuration file contains information that is read
                     16: by the resolver routines the first time they are invoked by a process.
                     17: The file is designed to be human readable and contains a list of
                     18: name-value pairs that provide various types of resolver information.
                     19: .LP
                     20: On a normally configured system this file should not be necessary.
                     21: The only name server to be queried will be on the local machine and 
                     22: the domain name is retrieved from the system.
                     23: .LP
                     24: The different configuration options are:
                     25: .TP
                     26: \fBnameserver\fP
                     27: followed by the Internet address (in dot notation) of a name server
                     28: that the resolver should query.  At least one name server should be
                     29: listed.  Up to MAXNS (currently 3) name servers may be listed, in that
                     30: case the resolver library queries tries them in the order listed.
                     31: If no \fBnameserver\fP entries are present,
                     32: the default is to use the name server on the local machine.
                     33: (The algorithm used is to try a name server, and if the query times out,
                     34: try the next, until out of name servers,
                     35: then repeat trying all the name servers
                     36: until a maximum number of retries are made).
                     37: .TP
                     38: \fBdomain\fP
                     39: followed by a domain name, that is
                     40: the default domain to append to names that do not have a dot in them.
                     41: If no \fBdomain\fP entries are present, the domain returned by
                     42: \fIgethostname\fP\|(2) is used (everything after the first `.').
                     43: Finally, if the host name does not contain a domain part, the root
                     44: domain is assumed.
                     45: .LP
                     46: The name value pair must appear on a single line, and the keyword
                     47: (e.g. \fBnameserver\fP) must start the line.  The value follows
                     48: the keyword, separated by white space.
