"""

# check the input

FeaturesVery simple to setup and deploy, yet very configurable Can use custom challenges (e.g. random chars, simple maths, dictionary word, ...) Custom generators, noise and filter functions alter the look of the generated image Supports text-to-speech audio output of the challenge text, for improved accessibility RequirementsDjango 1.0+ A fairly recent version of the Python Imaging Library (PIL) compiled with FreeType support Flite is required for text-to-speech (audio) output, but not mandatory InstallationDownload the 'captcha' application and put it anywhere in your Python path (or using setuptools: sudo easy_install django-simple-captcha) Add 'captcha' to the INSTALLED_APPS in your settings.py Run manage.py syncdb to create the required database tables Add an entry to your urls.py: urlpatterns += patterns('',
