The script isn't fully finished, but a few things are known and unlikely to change.
It is written in python3 and needs requests, psycopg2, and yaml modules. On debian these are packaged as python3-requests, python3-psycopg2, and python3-yaml.
Additionally ogr2ogr is required, packaged as gdal-bin. 2.0+ is preferred, but I *think* I can get 1.10 to work.
