2617     command <X>

  2618     -----------

  2619 

  2620     Send a request to run a named command, whose name follows the ``command``

  2621     string.

  2622 

  2623     Arguments to the command are defined as lines in this block. The format of

  2624     each line is ``<key> <value>``. e.g.::

  2625 

  2626        command listkeys

  2627            namespace bookmarks

  2628 

  2629     Values are interpreted as Python b'' literals. This allows encoding

  2630     special byte sequences via backslash escaping.
