This software, consisting of a daemon and a command shell, is meant to be 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.

The software is intended to be run as a GNU/Linux service that always runs in the background and can be used to both receive location updates from a remote tracker as well as configuring the tracker (over both USB and a GPRS link to the device).

All received events are stored in a database and the daemon supports export of events to GPX, KML, CSV format. It is also possible to have specific action scripts executed upon receiving specific events or generate mail notifications.

The daemon and command shell comes with extensive reference documentation (HTML & PDF) and Unix man pages.
