`inspectdir`

Stream [x, y, z]s of a directory

untiler inspectdir [OPTIONS] INPUT_DIR

Options:
-z, --zoom INTEGER  Zoom to inspect [default = all]
--help              Show this message and exit.

Outputs a line-delimited stream of tile [x, y, z]s; useful to pipe into mercantile shapes to visualize geometry:
