# Description:
#
#    This script outputs a JSON array with all the environment names defined in
#    platformio.ini.
#    It is used by this project's GitHub CI workflow.
#
#    Note that it expects to be executed from the project root directory. That is,
#    it needs to be run like this:
#
#    $ tools/show_envs.py
#
#    Instead of:
#
#    $ cd tools
#    $ ./show_envs.py
