-# NOTE
-# Why do we do we need the "!= main" check? Because if you run
-# wvtest.py as a main program and it imports your test files, then
-# those test files will try to import the wvtest module recursively.
-# That actually *works* fine, because we don't run this main program
-# when we're imported as a module. But you end up with two separate
-# wvtest modules, the one that gets imported, and the one that's the
-# main program. Each of them would have duplicated global variables
-# (most importantly, wvtest._registered), and so screwy things could
-# happen. Thus, we make the main program module *totally* different
-# from the imported module. Then we import wvtest (the module) into
-# wvtest (the main program) here and make sure to refer to the right
-# versions of global variables.
-#
-# All this is done just so that wvtest.py can be a single file that's
-# easy to import into your own applications.
