# Manual test procedure: get Zephyr Kernel, build an example, and run in Qemu:
#
# $ wget https://github.com/zephyrproject-rtos/zephyr/archive/master.tar.gz
# $ tar xf master.tar.gz
# $ cd zephyr-master/samples/synchronization
# $ mkdir build && cd build
# $ cmake -GNinja -DBOARD=qemu_cortex_m3 ..
# $ ninja run
#
# Should get output like:
#   ***** BOOTING ZEPHYR OS v1.8.99 - BUILD: Jun 27 2017 13:09:26 *****
#   threadA: Hello World from arm!
