    L{ListenFDs} provides access to file descriptors inherited from systemd.

Typically L{ListenFDs.fromEnvironment} should be used to construct a new
    instance of L{ListenFDs}.

@cvar _START: File descriptors inherited from systemd are always
        consecutively numbered, with a fixed lowest "starting" descriptor.  This
        gives the default starting descriptor.  Since this must agree with the
        value systemd is using, it typically should not be overridden.

@ivar _descriptors: A C{list} of C{int} giving the descriptors which were
        inherited.

        @param environ: A dictionary-like object to inspect to discover
            inherited descriptors.  By default, L{None}, indicating that the
            real process environment should be inspected.  The default is
            suitable for typical usage.

@param start: An integer giving the lowest value of an inherited
            descriptor systemd will give us.  By default, L{None}, indicating
            the known correct (that is, in agreement with systemd) value will be
            used.  The default is suitable for typical usage.

@return: A new instance of C{cls} which can be used to look up the
            descriptors which have been inherited.
