The +document is only transfered if the remote copy is newer than the local +copy. If the local copy is newer nothing happens. + +Use the C<-v> option to print the version number of this program. + +The timeout value specified with the C<-t> option. The timeout value +is the time that the program will wait for response from the remote +server before it fails. The default unit for the timeout value is +seconds. You might append "m" or "h" to the timeout value to make it +minutes or hours, respectively. + +Because this program is implemented using the LWP library, it only +supports the protocols that LWP supports. + +=head1 SEE ALSO + +L<lwp-request>, L<LWP> + +=head1 AUTHOR + +Gisle Aas <gisle@aas.no> + +=cut + + +use LWP::Simple qw(mirror is_success status_message $ua); +use Getopt::Std; + +$progname = $0; +$progname =~ s,.*/,,; # use basename only +$progname =~ s/\.\w*$//; #strip extension if any + +$VERSION = "5.810"; + +$opt_h = undef; # print usage +$opt_v = undef; # print version +$opt_t = undef; # timeout + +unless (getopts("hvt:")) { + usage(); +} + +if ($opt_v) { + require LWP; + my $DISTNAME = 'libwww-perl-' .
