   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.
