10 * This program exposes the C API of the configuration mechanism
11 * as a set of simple commands in order to facilitate testing.
12 *
13 * Reads stdin and prints result of command to stdout:
14 *
15 * get_value -> prints the value with highest priority for the entered key
16 *
17 * get_value_multi -> prints all values for the entered key in increasing order
18 * of priority
19 *
20 * get -> print return value for the entered key
21 *
22 * get_int -> print integer value for the entered key or die
23 *
24 * get_bool -> print bool value for the entered key or die
25 *
26 * get_string -> print string value for the entered key or die
27 *
28 * configset_get_value -> returns value with the highest priority for the entered key
29 * from a config_set constructed from files entered as arguments.
30 *
31 * configset_get_value_multi -> returns value_list for the entered key sorted in
32 * ascending order of priority from a config_set
33 * constructed from files entered as arguments.
34 *
35 * iterate -> iterate over all values using repo_config(), and print some
36 * data for each
37 *
38 * git_config_int -> iterate over all values using repo_config() and print the
39 * integer value for the entered key or die
40 *
41 * Examples:
42 *
43 * To print the value with highest priority for key "foo.bAr Baz.rock":
44 * test-tool config get_value "foo.bAr Baz.rock"
45 *
