Emaigos is a free software written in Lazarus and useful to import Google contacts and calendars in Emacs (
http://www.gnu.org/software/emacs). Contacts are stored in a Big Brother Database (
http://savannah.nongnu.org/projects/bbdb) file, which makes them usable with many Emacs email packages, like Gnus (
http://www.gnus.org). Google calendars are stored as a single Org mode (
http://orgmode.org) file, so that the events may be viewed as a structured document and possibly shown within an Agenda view. So with Emaigos it's possible to use Google as contacts and calendars manager, while having at the same time all data available within Emacs.
