=head1 NAME

ip2cc - lookup country from IP address or hostname

=head1 SYNOPSIS

ip2cc [host-to-find]

=head1 DESCRIPTION

Ip2cc is a program to lookup countries of IP addresses. Ip2cc
has two modes: interactive and non-interactive.  Interactive mode allows
the user to query more than one hostname.  Non-interactive mode is
used to print just the country for a single host.

=head1 ARGUMENTS

Interactive mode is entered when no arguments are given.

Non-interactive mode is used when the name or Internet address of the
host to be looked up is given as the first argument.

=head1 SEE ALSO

IP::Country - the fast database used by this script.
