The idea is that this tool contains script to download (i.e. slurp) commonly used datasets and to register them in a postgresql+postgis database. This database can then be queried allowing the retrieval of the relevant data or datafiles.
The main documentation lives at wobbly.earth/geoslurp
The geoslurp module itself is a pure python module, which acts as a client. For this to work one needs to set up a running PostGreSQL database.
