   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 *
