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 *
