- # Why do we do this in such a convoluted way? Because if you run

- # 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.
