 ## Core functionality
 
 The command line tool can do the following things:
 
-- Send unary rpc.
-- Attach metadata and display received metadata.
-- Handle common authentication to server.
-- Infer request/response types from server reflection result.
-- Find the request/response types from a given proto file.
-- Read proto request in text form.
-- Read request in wire form (for protobuf messages, this means serialized binary form).
-- Display proto response in text form.
-- Write response in wire form to a file.

 The command line tool should support the following things:
 
-- List server services and methods through server reflection.
-- Fine-grained auth control (such as, use this oauth token to talk to the server).
-- Send streaming rpc.
