   6 * This program exposes the C API of the configuration mechanism
   7 * as a set of simple commands in order to facilitate testing.
   8 *
   9 * Reads stdin and prints result of command to stdout:
  10 *
  11 * get_value -> prints the value with highest priority for the entered key
  12 *
  13 * get_value_multi -> prints all values for the entered key in increasing order
  14 *                   of priority
  15 *
  16 * get_int -> print integer value for the entered key or die
  17 *
  18 * get_bool -> print bool value for the entered key or die
  19 *
  20 * get_string -> print string value for the entered key or die
  21 *
  22 * configset_get_value -> returns value with the highest priority for the entered key
  23 *                      from a config_set constructed from files entered as arguments.
  24 *
  25 * configset_get_value_multi -> returns value_list for the entered key sorted in
  26 *                              ascending order of priority from a config_set
  27 *                              constructed from files entered as arguments.
  28 *
  29 * iterate -> iterate over all values using git_config(), and print some
  30 *            data for each
  31 *
  32 * Examples:
  33 *
  34 * To print the value with highest priority for key "foo.bAr Baz.rock":
  35 *      test-config get_value "foo.bAr Baz.rock"
  36 *
