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 *
