+ * ATTENTION: this is just kludge!
+ * They are not really unit tests, but rather tests of the whole process,
+ * from source file loading all the way through to running 64tass.
+ * What's more: in case of failure (to compile and assemble) - which is when tests should help you -
+ * these tests will actually be ignored (ie. NOT fail),
+ * because in the code there are calls to Process.exit, making it essentially untestable.
