Something like:

    This string contains a platform identifier that can be used to append

    For other systems, the values are:
 
    ================ ===========================
    System           :data:`platform` value
    ================ ===========================

    Windows/Cygwin   ``'cygwin'``

I don't think that I need a :versionchanged:`2.7.3`.
