  Usage:

      TOKEN=token AT=TIME_DETLA $0 stream - to stream deltas       # will stream deltas
      TOKEN=token AT=TIME_DELTA $0 cursor                          # will return a Nylas cursor
      TOKEN=token $0 [get|post|delete|head|put] /ENDPOINT [ARGS]   # will hit Nylas
      TOKEN=token $0 search "from:[email protected]"                     # will search for threads
      TOKEN=token $0 download FILE_ID                              # will download a file locally

  Examples:

      TOKEN=token AT=-1H $0 stream --data-urlencode "include_types=file" |jq
      TOKEN=token AT=-3M $0 cursor
      TOKEN=token $0 get /messages/:id
      TOKEN=token $0 get /files/:id
      TOKEN=token $0 put /threads/:id -d '{"folder_id":FOLDER_ID}'
