g7ctrl is a daemon and a command shell that are used together with the Xtreme GM7 GPS tracker to help simplify its management and to make it possible to monitor alerts sent by the tracker. It is designed to run in the background and can be used to both receive location updates from a remote tracker and configure a tracker over USB. All received events are stored in a database and can be exported to GPX, KML, and CSV, with distances calculated. It can also execute action scripts upon receiving specific events or generate mail notifications. Extensive reference documentation (HTML and PDF) and Unix man pages are provided.
