How do I access the clientutils module?

Access to this module would make life a lot easier for me. The reason I looked into django-casper was to test code that uses a form's submit button to download a file. The base64decode() example was useful for me to retrieve a file via a POST request, but I need to decode the file, and that requires the clientutils module.

Help! Or a workaround, where I don't need to encode then decode the file I get from a POST request. :-)

Thanks!
