WebBot is a Web development toolset which is designed to sit nicely on top of your existing infrastructure. It is built with a collection of Open Source tools which together enable building Python Web applications the same way native ones are built and running these applications on top of the leading Python frameworks (such as Django and Google's App Engine). As a result, the WebBot framework encourages reuse, concise code, rapid development, and happy developers.
Google Apps Improved Login (GAIL) provides Google Apps administrators with two oft-requested features: the ability to customize the login page and the ability to log in as their users. GAIL is designed to run on Google's App Engine so that administrators do not need to have their own Web server. GAIL works by making use of the SAML Single Sign-On (SSO) Service for Google Apps. Premier and Education Editions of Google Apps are supported. Standard Edition is not.
