# Modified by Leigh Wedding <leigh.wedding@telstra.com> to build with
# Kerberos support.  Note: requires MIT Kerberos to be installed.  Generated
# package also relies in standard Slackware openssh package being installed.
# Generated package does not overwrite or interfere with the standard
# Slackware openssh package.
