           Allows you to make a raw Conduit method call:
 
             - Run this command from a working directory.
             - Call parameters are REQUIRED and read as a JSON blob from stdin.
             - Results are written to stdout as a JSON blob.
 
           This workflow is primarily useful for writing scripts which integrate
           with Phabricator. Examples:
 
             $ echo '{}' | arc call-conduit conduit.ping
             $ echo '{"phid":"PHID-FILE-xxxx"}' | arc call-conduit file.download
