/* This header defines an interface that must be used by program linked
    with the various Unix Glk libraries -- at least, the three I wrote.
    (I encourage anyone writing a Unix Glk library to use this interface,
    but it's not part of the Glk spec.)
    
    Because Glk is *almost* perfectly portable, this interface *almost*
    doesn't have to exist. In practice, it's small.
