### Build flavors/types ###

When building for a particular product, it's often useful to have minor variations on what is ultimately the final release build. These are the currently-defined "flavors" or "types" (we need to settle on a real name for these).

If you build one flavor and then want to build another, you should run "`make installclean`" between the two makes to guarantee that you don't pick up files installed by the previous flavor. "`make clean`" will also suffice, but it takes a lot longer.
