 * sshconfig.php
 * --------
 * Author: Kevin Ernst (kevin.ernst -at- cchmc.org)
 * Copyright: (c) 2017 Kevin Ernst
 * Release Version: 1.0.9.1
 * Date Started: 2017/12/01
 *
 * OpenSSH config file (~/.ssh/config) language file for GeSHi.
 *
 * CHANGES
 * -------
 * 2017/12/02 (1.0.0)
 *   -  First release; couldn't figure out how to separately highlight negated
        hostnames/wildcards, but it's good enough for a basic ~/.ssh/config
