How to make it usable as a library or in cli

[JeanMenage]

Hi, i'm using python and i would like to use that navfile reader, however since it's not a library, i'm struggling while trying to use it. i've tried a lot of things from converters to wrappers, however nothing worked so far. So i was wondering if it could be used as a library, which would make it way more easier to use from any other languages, or even make it usable in cli (like from the command prompt 'navfile_reader map_name.nav') . Thanks !
