This directory contains a version of the stack development with
the following components:

stack.[ch]: stub stack implementation
test1.c:    first test case using CHECK_* macros
Makefile:   fully functional Makefile to compile and test test1
checker:    fully functional perl script
bool.h:     basic boolean type
check.h:    the CHECK_* macros

RESULT:     test1 fails because isempty() is still a stub.
	    still, at least test1 prints a prettier message!
