1  /* Miniature re-implementation of the "check" library.
       2  
       3     This is intended to support just enough of check to run the Expat
       4     tests.  This interface is based entirely on the portion of the
       5     check library being used.
       6  
       7     This is *source* compatible, but not necessary *link* compatible.
