description         OpenSSH secure login server

long_description    OpenSSH is a FREE version of the SSH protocol suite of \
                    network connectivity tools that increasing numbers of people on the \
                    Internet are coming to rely on. Many users of telnet, rlogin, ftp, \
                    and other such programs might not realize that their password is \
                    transmitted across the Internet unencrypted, but it is. OpenSSH \
                    encrypts all traffic (including passwords) to effectively eliminate \
                    eavesdropping, connection hijacking, and other network-level \
                    attacks. Additionally, OpenSSH provides a myriad of secure \
                    tunneling capabilities, as well as a variety of authentication \
                    methods.

    #   when run as root, so it can't be used for authentication. This patch just
    #   forces the use of PAM regardless of the configuration.
    # - patch-*-apple-sandbox-named-external.diff
    #   Use Apple's sandbox_init(3) in addition to standard privilege separation.
    #   This requires a sandbox profile (which we provide) and the sandbox_init(3)
    #   call before the chroot(2) to privsep-path (${prefix}/var/empty), or it will
    #   fail to load the sandbox description and libsandbox.1.dylib.
    # - macports-config.patch
    #   Changes the default configuration from the upstream-provided one by popular
    #   request.
    # - agent.patch
    #   Adds -l flag to ssh-agent to work with launchd.
