How to get started:

chmod +x parser.py
./parser libraries_path [--platform {win, lin, mac}]

libraries_path - required parameter. May be absolute or relative.
--platform - optional parameter. Value can be one of {win, lin, mac}. If not specified, defaults to 'all' - in this case, runs for all three platforms.

Examples:

python3 parser.py ./libraries

or

./parser.py libraries --platform win
