# gps-share: <https://github.com/zeenix/gps-share>
# takes a local GPS device (e.g. /dev/ttyUSB1) and makes it available over TCP/Avahi (multicast DNS).
#
# common usecases:
# 1. make positioning available to any device on a network, even if that device has no local GPS
# - e.g. my desktop can use my phone's GPS device, if on the same network.
# 2. allow multiple clients to share a GPS device.
# GPS devices are serial devices, and so only one process can consume the data at a time.
# gps-share can camp the serial device, and then allow *multiple* subscribers
# 3. provide a *read-only* API to clients like Geoclue.
# that is, expose the GPS device *output* to a client, but don't let the client write to the device (e.g. enable/disable the GPS).
# this is the primary function i derive from gps-share
