+-c citc_client_to_query_for_android_libraries:
+  Name of the CITC client to query for Android libraries.  This will perform
+  a blaze query at the head of this client.
+-t target_citc_client_to_add_android_libraries_to:
+  Name of the CITC client to add Android libraries to.
+-b branch_name:
+  Name of the branch in the target CITC client to modify.
+  e.g firebase.cpp_release_branch/281913092.1
+  You can retrieve the branch associated with a candidate by:
+  - Navigating to a Rapid project in the web UI http://rapid
+  - Reading the Branch string
+  You can checkout a candidate's branch using 'rapid-tool checkout_branch'
+-d:
+  Print branch commands without executing them.
+-h:
+  Display this help message.
