17# Usage:
18# 1. Run envsetup and lunch first in an Android checkout
19# 2. Make target bluetooth_packets_python3 that will generate C++ sources for the
20#    Extension
21# 3. Build only:
22#       python3 bluetooth_packets_python3_setup.py build_ext
23#   Then Find the .so file in build/lib.linux-x86_64-3.X
24# 4. Install:
25#       python3 bluetooth_packets_python3_setup.py install --user
