# Test 1: Check for headers without #pragma once
# - Ignore third party libraries
# - Ignore the file md32_common.h which is included several times in different
#   contexts (TODO:Fix this)
# - If the last grep did not match any file (success) it returns an error code
#   that terminates the script. We avoid this by adding the final '|| true'
