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.
tadedon is a set of utilities that form a foundation for applications written with one of the many Java frameworks, such as GWT, GIN, Guice, Google App Engine, commons-configuration, and many others. It lets you specify the default configuration of your application and upgrade it automatically on each new release. It can redirect all java.util.logging to slf4j and easily configure logback. It can bind application configuration in a Guice module. It supports @PostConstruct and @PreDestroy annotations (JSR 250) in Guice applications. It lets you annotate your methods with @Transactional annotation. It supports Guice injector stage in your Web application. It lets you test your Guice managed servlets and filters without needing a real servlet container. It lets you use Guice Matchers for matching super class, interface, and type literal annotations. It can inject event bus to your GWT applications with the help of GIN.
Google Apps Manager (GAM) is a command line tool that allows Administrators to control their Google Apps domain and accounts. With GAM you can create users, turn on/off services for users like POP and Forwarding and much more. It requires Google Apps Education or Premier Edition. Standard Edition is not supported. Future plans for GAM include even more management capabilities as well as a graphical and Web-based interface.
Emaigos imports Google contacts and calendars into Emacs. Contacts are stored in a Big Brother Database (BBDB) file, which makes them usable with many Emacs email packages, like Gnus. Google calendars are stored as a single Org-mode file, so events may be viewed as a structured document and possibly shown within an Agenda view. With Emaigos, it's possible to use Google as a contacts and calendars manager, while having all the same data available within Emacs. The original Google contacts and calendars are not modified in any way by Emaigos. The name "Emaigos" is an acronym for "EMAcs Importer for GOogle Stuff".
gdata-python-scripts collects some simple scripts and examples that use the Google Spreadsheets Data APIs client libraries for Python. The main goal is to collect and publish small snippets of code that, if not completely general and ready to use, remain simple enoguh (and hopefully well documented enough) to be adapted to your own needs.
