Highly flexible, no magic input validation library

Pycerberus is a framework to check user data thoroughly so that you can protect your application from malicious (or just garbled) input data. * Remove stupid code which converts input values: After values are validated, you can work with real Python types instead of strings - e.g. 42 instead of '42', convert database IDs to model objects transparently. * Implement custom validation rules: Writing custom validators is straightforward, everything is well documented and pycerberus only uses very little Python magic. * Focus on your value-adding application code: Save time by implementing every input validation rule only once, but 100% right instead of implementing a dozen different half-baked solutions. * Ready for global business: i18n support (based on GNU gettext) is built in, adding custom translations is easy. * Tune it for your needs: You can implement custom behavior in your validators, e.g. fetch translations from a database instead of using gettext or define custom translations for built-in validators. * Use it wherever you like: pycerberus is used in a SMTP server, trac macros as well as web applications - there are no dependecies on a specific context like web development.
