def serverFromString(reactor, description):
    """
    Construct a stream server endpoint from an endpoint description string.

    The format for server endpoint descriptions is a simple string.  It is a
    prefix naming the type of endpoint, then a colon, then the arguments for
    that endpoint.

    For example, you can call it like this to create an endpoint that will
    listen on TCP port 80::

        serverFromString(reactor, "tcp:80")

    Additional arguments may be specified as keywords, separated with colons.
    For example, you can specify the interface for a TCP server endpoint to
    bind to like this::

        serverFromString(reactor, "tcp:80:interface=127.0.0.1")

    SSL server endpoints may be specified with the 'ssl' prefix, and the
    private key and certificate files may be specified by the C{privateKey} and
    C{certKey} arguments::

        serverFromString(reactor, "ssl:443:privateKey=key.pem:certKey=crt.pem")

    If a private key file name (C{privateKey}) isn't provided, a "server.pem"
    file is assumed to exist which contains the private key. If the certificate
    file name (C{certKey}) isn't provided, the private key file is assumed to
    contain the certificate as well.

    You may escape colons in arguments with a backslash, which you will need to
    use if you want to specify a full pathname argument on Windows::

        serverFromString(reactor,
            "ssl:443:privateKey=C\\:/key.pem:certKey=C\\:/cert.pem")

    finally, the 'unix' prefix may be used to specify a filesystem UNIX socket,
    optionally with a 'mode' argument to specify the mode of the socket file
    created by C{listen}::

        serverFromString(reactor, "unix:/var/run/finger")
        serverFromString(reactor, "unix:/var/run/finger:mode=660")

    This function is also extensible; new endpoint types may be registered as
    L{IStreamServerEndpointStringParser} plugins.  See that interface for more
    information.

    @param reactor: The server endpoint will be constructed with this reactor.

    @param description: The strports description to parse.

    @return: A new endpoint which can be used to listen with the parameters
        given by by C{description}.

    @rtype: L{IStreamServerEndpoint<twisted.internet.interfaces.IStreamServerEndpoint>}

    @raise ValueError: when the 'description' string cannot be parsed.

    @since: 10.2
