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.
