Usage:
sh build.sh <command> [target]

Commands:
  help|usage|-h|--help: Shows this message.
  list|-l: List firmwares available to build.
  build-firmware <target>: Build the firmware for the given build target.
  build-firmwares: Build all firmwares for all targets.
  build-matching-firmwares <build-match-spec>: Build all firmwares for build targets containing the string given for <build-match-spec>.
  build-companion-firmwares: Build all companion firmwares for all build targets.
  build-repeater-firmwares: Build all repeater firmwares for all build targets.
  build-room-server-firmwares: Build all chat room server firmwares for all build targets.

Examples:
Build firmware for the "RAK_4631_repeater" device target
$ sh build.sh build-firmware RAK_4631_repeater

Build all firmwares for device targets containing the string "RAK_4631"
$ sh build.sh build-matching-firmwares <build-match-spec>

Build all companion firmwares
$ sh build.sh build-companion-firmwares

Build all repeater firmwares
$ sh build.sh build-repeater-firmwares

Build all chat room server firmwares
$ sh build.sh build-room-server-firmwares

Build all kiss radio firmwares
$ sh build.sh build-kiss-radio-firmwares

Environment Variables:
  DISABLE_DEBUG=1: Disables all debug logging flags (MESH_DEBUG, MESH_PACKET_LOGGING, etc.)
                   If not set, debug flags from variant platformio.ini files are used.

Examples:
Build without debug logging:
$ export FIRMWARE_VERSION=v1.0.0
$ export DISABLE_DEBUG=1
$ sh build.sh build-firmware RAK_4631_repeater

Build with debug logging (default, uses flags from variant files):
$ export FIRMWARE_VERSION=v1.0.0
$ sh build.sh build-firmware RAK_4631_repeater
