D&D 5e Framework for MapTool, based on the work of the RPTools.net forum.
Navigate to the compile directory, and run the compile-campaign.sh file. This will zip the contents of the repository into a CMPGN file.
Having built your CMPGN file, open it up in MapTools and make your edits there. Once you've saved the file, run the extract-campaign.sh file. This should overwrite the repository's framework folder, and replace it with your edited output.
