 /*
-  A command line tool to talk to any grpc server.
+  A command line tool to talk to a grpc server.
   Example of talking to grpc interop server:
-  1. Prepare request binary file:
-    a. create a text file input.txt, containing the following:
-        response_size: 10
-        payload: {
-          body: "hello world"
-        }
-    b. under grpc/ run
-        protoc --proto_path=src/proto/grpc/testing/ \
-        --encode=grpc.testing.SimpleRequest
-  src/proto/grpc/testing/messages.proto \
-        < input.txt > input.bin
-  2. Start a server
-    make interop_server && bins/opt/interop_server --port=50051
-  3. Run the tool
-    make grpc_cli && bins/opt/grpc_cli call localhost:50051 \
-    /grpc.testing.TestService/UnaryCall --enable_ssl=false \
-    --input_binary_file=input.bin --output_binary_file=output.bin
-  4. Decode response
-    protoc --proto_path=src/proto/grpc/testing/ \
-    --decode=grpc.testing.SimpleResponse src/proto/grpc/testing/messages.proto \
-    < output.bin > output.txt
-  5. Now the text form of response should be in output.txt
-  Optionally, metadata can be passed to server via flag --metadata, e.g.
-    --metadata="MyHeaderKey1:Value1:MyHeaderKey2:Value2"
+  grpc_cli call localhost:50051 UnaryCall src/proto/grpc/testing/test.proto \
+    "response_size:10"  --enable_ssl=false
+
+  Options:
+    1. --proto_path, if your proto file is not under current working directory,
+       use this flag to provide a search root. It should work similar to the
+       counterpart in protoc.
+    2. --metadata specifies metadata to be sent to the server, such as:
+       --metadata="MyHeaderKey1:Value1:MyHeaderKey2:Value2"
+    3. --enable_ssl, whether to use tls.
+    4. --use_auth, if set to true, attach a GoogleDefaultCredentials to the call
+    3. --input_binary_file, a file containing the serialized request. The file
+       can be generated by calling something like:
+       protoc --proto_path=src/proto/grpc/testing/ \
+         --encode=grpc.testing.SimpleRequest \
+         src/proto/grpc/testing/messages.proto \
+         < input.txt > input.bin
+       If this is used and no proto file is provided in the argument list, the
+       method string has to be exact in the form of /package.service/method.
+    4. --output_binary_file, a file to write binary format response into, it can
+       be later decoded using protoc:
+       protoc --proto_path=src/proto/grpc/testing/ \
+       --decode=grpc.testing.SimpleResponse \
+       src/proto/grpc/testing/messages.proto \
+       < output.bin > output.txt
