# CheckSocket

A very simple Perl 6 function to test if a TCP socket is listening on
a given address.

## Description

This module provides a very simple mechanism to determine whether
something is listening on a TCP socket at the given port and address.
This is primarly for the convenience of testing where there may be a
dependency on an external network service.  For example:

    use Test;
    use CheckSocket;

    if not check-socket(80, "localhost") {
             skip-all "no web server";
        exit;
    }

       # or

       use Test;
       use CheckSocket;

       # Start some socket server concurrently
       if wait-socket(80, "localhost") {
               # do some tests
       }
       else {
               skip-all "server didn't start in time";
       }

## Installation
