+ * This header file provides a friendlier API to the test-convey framework.
+ * It basically provides some "friendly" names for symbols to use instead of
+ * the test_xxx symbols.  Basically we pollute your namespace, for your
+ * benefit.  Don't like the pollution?  Use test.h instead.

+ * This test framework allows one to write tests as a form of assertion,
+ * giving simpler and more readable test logic.
+ *
+ * The test framework provides a main() function.
+ *
+ * To use this call the test_main() macro, and embed test_convey() references.
+ * These can be nested, and after each convey the entire stack is popped so
+ * that execution can continue from the beginning, giving each test section
+ * the same environment.
+ *
+ * There are assertion macros too, which don't roll back the stack, but which
+ * do update the test state.
+ *
+ * Here's a sample file:
+ *
+ * TestMain("Integer Tests", {
+ *	int x = 1; int y = 2;
+ *	Convey("Addition works", func() {
+ *		So(y == 2);
+ *		So(y + x == 3);
+ *		So(x + y == 3);
+ *		Convey("Even big numbers", func() {
+ *			y = 100;
+ *			So(x + y == 101);
+ *		});
+ *		Convey("Notice y is still 2 in this context", func() {
+ *			So(y == 2);
+ *		});
+ * 	});
+ * })
+ * 
+ * There are other macros, but this is a work in progress.  The inspiration
+ * for this is from GoConvey -- github.com/smartystreets/goconvey - but this
+ * is a version for C programs.
+ *
+ * In addition to the names listed here, your test code should avoid using
+ * names beginning with "test_" or "T_" as we use those names internally
+ * in macros, which may collide or do other bad things with your names.
+ */

+/*
+ * TestMain is used to generate a main() function that runs your code,
