+CONTROL                        <command>|[<parameters>|]
+       Send a control command <command> with optional parameters
+       (<parameters>) to Xenstore daemon.
+
+       The set of commands and their semantics is implementation
+       specific and is likely to change from one Xen version to the
+       next.  Out-of-tree users will encounter compatibility issues.
+
+       Current commands are:
+       check
+               checks xenstored innards
+       log|on
+               turn xenstore logging on
+       log|off
+               turn xenstore logging off
+       logfile|<file-name>
+               log to specified file
+       memreport|[<file-name>]
+               print memory statistics to logfile (no <file-name>
+               specified) or to specific file
+       print|<string>
+               print <string> to syslog (xenstore runs as daemon) or
+               to console (xenstore runs as stubdom)
+       help                    <supported-commands>
+               return list of supported commands for CONTROL
+

+       Deprecated, now named CONTROL
