   5  * This program exposes the C API of the configuration mechanism
   6  * as a set of simple commands in order to facilitate testing.
   7  *
   8  * Reads stdin and prints result of command to stdout:
   9  *
  10  * get_value -> prints the value with highest priority for the entered key
  11  *
  12  * get_value_multi -> prints all values for the entered key in increasing order
  13  *                   of priority
  14  *
  15  * get_int -> print integer value for the entered key or die
  16  *
  17  * get_bool -> print bool value for the entered key or die
  18  *
  19  * get_string -> print string value for the entered key or die
  20  *
  21  * configset_get_value -> returns value with the highest priority for the entered key
  22  *                      from a config_set constructed from files entered as arguments.
  23  *
  24  * configset_get_value_multi -> returns value_list for the entered key sorted in
  25  *                              ascending order of priority from a config_set
  26  *                              constructed from files entered as arguments.
  27  *
  28  * Examples:
  29  *
  30  * To print the value with highest priority for key "foo.bAr Baz.rock":
  31  *      test-config get_value "foo.bAr Baz.rock"
  32  *
