=item B<-l> I<address>
Tells the daemon to bind to I<address> and accept incoming connections on that
-socket. If I<address> begins with C<unix:>, everthing following that prefix is
+socket. If I<address> begins with C<unix:>, everything following that prefix is
interpreted as the path to a UNIX domain socket. Otherwise the address or node
name are resolved using L<getaddrinfo(3)>.
+If the B<-l> option is not specified the default address,
+C<unix:/tmp/rrdcached.sock>, will be used.

=item B<-w> I<timeout>
-Data is written to disk every I<timeout> seconds.
+Data is written to disk every I<timeout> seconds. If this option is not
+specified the default interval of 300E<nbsp>seconds will be used.
=item B<-f> I<timeout>
Every I<timeout> seconds the entire cache is searched for old values which are
written to disk. This only concerns files to which updates have stopped, so
-setting this to a high value, such as 3600 seconds, is acceptable in most
-cases.
+setting this to a high value, such as 3600E<nbsp>seconds, is acceptable in most
