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".
GCalert will access all your Google calendars and display alarms via libnotify for whenever you have alarms set for each event. These alarm widgets do not receive focus (and thus do not take keyboard input away from other applications), yet are clearly visible even on a cluttered desktop.
Googsystray is a system tray app for Google Voice, GMail, Google Calendar, Google Reader, and Google Docs. It lets you keep track of the information provided by those services without having to keep a bunch of Web pages open or constantly checking them. It notifies you of new events, such as messages or alerts, and provides basic services quickly.
Google Custom Search is a class that performs searches against a Google Custom Search engine, processing the response (search results and/or spelling suggestions) into properties of the object. It uses either cURL or the HTTP stream wrapper, depending on what is available on the server. The user can also specify the character encoding for the search query. Results are also made available in that encoding.
Search Engine Referrals Confluence Plugin is a Confluence plugin that displays the most recent searches on Google. When someone enters search terms on Google and clicks on one of the search results, the search terms are sent to the found Web site in the "referer" part of the HTTP request. This plugin collects this information and displays it to the user. A click on the search result opens the page Google has found. A click on the search engine icon at the left displays the corresponding Google search result page.
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.
