--- Ways
-
--- The central concept of a "way" is that all objects in a given
--- program must be compiled in the same "way". Certain options change
--- parameters of the virtual machine, eg. profiling adds an extra word
--- to the object header, so profiling objects cannot be linked with
--- non-profiling objects.
-
--- After parsing the command-line options, we determine which "way" we
--- are building - this might be a combination way, eg. profiling+ticky-ticky.
-
--- We then find the "build-tag" associated with this way, and this
--- becomes the suffix used to find .hi files and libraries used in
--- this compilation.
