=head1 NAME

Test::TCP::CheckPort - check if a port is open from command line


  $^X -MTest::TCP::CheckPort -echeck_port 8080


This is a wrapper for L<Net::EmptyPort> which checks if a given port
is open, from the command line argument (C<@ARGV>). Because it works
with port numbers in the argument list, you don't need to quote it
when running with the perl executable.
