landsat search query using shapefile as input?

I’ve been using your landsat-util and it’s working great so far. I have a question about this functionality listed on the website:

"Landsat-util also makes it easier to find the imagery for a specific area. You can point it to a local shapefile and landsat-util selects all images that cover your shapefile. If you give a country, landsat-util selects all images that cover that country."

The commands I found online never seemed to be accepted. If I have a local shape file how should I run this query correctly? I’m doing something like:

$: landsat search --cloud 6 --start "july 01 2013" --end "may 1 2015" /home/user/tmp/4_tile_test/4_tiles.shp

The error returned is this:

Error: unrecognized arguments: /home/user/tmp/4_tile_test/4_tiles.shp

Does landsat-util even support this feature?
