#
# Blue Horizon Firmware Device API: gps
#
# This server provides REST access to gps receiver location and satellite data
#
# More precise documentation of the behavior of this container may be found
# in the src/main.go source code.
#
# To build this server container, run the following command in this directory:
#   $ make
#
# To run the firmware container as a daemon process (e.g., so you can test it):
#   $ make daemon
#
# To run the firmware container in dev mode (normally used for development):
#   $ make develop
