|Gypsy Reference Manual|
Gypsy is a GPS multiplexer daemon for allowing multiple location-aware programs to receive data from the same GPS device. Gypsy was designed for all manner of systems from the high end desktops and laptops, right down to low power handheld systems and mobile phones.
Gypsy comes with two components. The first, called gypsy-daemon, is the actual program that sits as a middle man between the GPS device and the client applications. Gypsy-daemon also parses the NMEA sentences from the GPS into a sensible format that applications can use. The second component is LibGypsy. This is a shared library that puts creates a C wrapper around the D-Bus interface, creating GObjects that emit signals and allow the user to control gypsy-daemon.
