+/**
+ *  -list-thread-groups [--available | GROUP]
+ *      
+ *  When used without GROUP parameter, this will list top-level 
+ *  thread groups that are being debugged.  When used with the GROUP 
+ *  parameter, the children of the specified group will be listed. 
+ *  The children can be either threads, or other groups. At present,
+ *  GDB will not report both threads and groups as children at the 
+ *  same time, but it may change in future.
+ *    
+ *  With the --available option, instead of reporting groups that are
+ *  being debugged, GDB will report all thread groups available on the 
+ *  target, not only the presently debugged ones. Using the --available 
+ *  option together with explicit GROUP is not likely to work on all targets.
+ *
+ *  The output of the command is:
+ *
+ *  ^done,threads=[<thread>],groups=[<group>]
+ *  
+ *  where each thread group is like this:
+ *  
+ *  {id="xxx",type="process",pid="yyy",num_children="1"}
+ *  
+ *  The id of a thread group should be considered an opaque string.
+ * @since 1.1
