``supermercado edges``
~~~~~~~~~~~~~~~~~~~~~~

::

<[x, y, z] stream> | supermercado edges | <[x, y, z] stream>

Outputs a stream of ``[x, y, z]``\ s representing the edge tiles of an
input stream of ``[x, y, z]``\ s. Edge tile = any tile that is either
directly adjacent to a tile that does not exist, or diagonal to an empty
tile.

``supermercado union``
~~~~~~~~~~~~~~~~~~~~~~

::

<[x, y, z] stream> | supermercado union | <{geojson} stream>

Outputs a stream of unioned GeoJSON from an input stream of
``[x, y, z]``\ s. Like ``mercantile shapes`` but as an overall footprint
instead of individual shapes for each tile.
