tippecanoe-enumerate
====================
The `tippecanoe-enumerate` utility lists the tiles that an `mbtiles` file defines.
Each line of the output lists the name of the `mbtiles` file and the zoom, x, and y
coordinates of one of the tiles.
tippecanoe-decode
=================
The `tippecanoe-decode` utility turns vector mbtiles back to GeoJSON. You can use it either
on an entire file:
tippecanoe-decode file.mbtiles
or on an individual tile:
tippecanoe-decode file.mbtiles zoom x y
If you decode an entire file, you get a nested `FeatureCollection` identifying each
tile and layer separately. Note that the same features generally appear at all zooms,
so the output for the file will have many copies of the same features at different
resolutions.
