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"
