   8     with the various Unix Glk libraries -- at least, the three I wrote.
   9     (I encourage anyone writing a Unix Glk library to use this interface,
  10     but it's not part of the Glk spec.)
  11
  12     Because Glk is *almost* perfectly portable, this interface *almost*
  13     doesn't have to exist. In practice, it's small.
