+Interface we want:
+    $ "tool" search planet <body-name> \
+                    in <region-label> \
+                    within <geometry> \
+                    [--inside|--touch] \
+                    at <datetime-moment> \
+                    between <datetime-range> \
+                    [--inclusive|--exclusive]
+
+    $ "tool" list {<query>, "last-query", or "query-label"}
+
+    $ "tool" get "data-ID" or "data-IDs"
+
+The 'list' command output will list data files/records IDs,
+and possibly (basic) metadata next to (e.g., bounding-box),
+in such a way that they can be easily retrived by command
+'get'. 'get' receives a (list of) data-ID(s) to download.
+
+> Internally, each data-ID -- represented by a unique string by the user -- 
+  should encapsulted in a query object, to then compose a list of queries to
+  be dispatched. This allows us to make query batch jobs, with more control
+  and possibly optimize/parallelize.
