The kodi_nfo_generator is a simple Python-based command-line tool that allows you to generate .nfo files for movies/TV shows that Kodi can use for its library.
This tool is aimed at people that manually curate their movie databases, in order to avoid using scrapers that may pull in the wrong information (or none at all). All the user has to do is place an ID file alongside their movie files, the default is *.imdb, containing the unique IMDB movie ID (or full IMDB movie URL). The tool will then scour the movie directories for these files and pull in the information and create the .nfo files in the same location.
It is also possible to pull in information about episodes of a TV series (--episodes). Though this is slow due to a lot more API calls. In this case, .nfo files for TV episodes are being generated. The episodes can either be in the same directory of the .nfo file of the series or in sub-directories.
