I would suggest staying with publisher for now as it is known to
correctly do the mapping of URL to Python object. Getting this all
right isn't simple. Get it wrong and you might end up with a security
hole. Also, in mod_python 3.2.7 publisher uses its own module
loader which solves a lot of problems. If you write your own dispatcher
and use apache.import_module(), you expose yourself to all the old
module importer problems again until apache.import_module() is
