| /* |
| * This program exposes the C API of the configuration mechanism |
| * as a set of simple commands in order to facilitate testing. |
| * |
| * Reads stdin and prints result of command to stdout: |
| * |
| * get_value -> prints the value with highest priority for the entered key |
| * |
| * get_value_multi -> prints all values for the entered key in increasing order |
| * of priority |
| * |
| * get_int -> print integer value for the entered key or die |
| * |
| * get_bool -> print bool value for the entered key or die |
| * |
| * get_string -> print string value for the entered key or die |
| * |
| * configset_get_value -> returns value with the highest priority for the entered key |
| * from a config_set constructed from files entered as arguments. |
| * |
| * configset_get_value_multi -> returns value_list for the entered key sorted in |
| * ascending order of priority from a config_set |
| * constructed from files entered as arguments. |
| * |
| * iterate -> iterate over all values using git_config(), and print some |
| * data for each |
| * |
| * Examples: |
| * |
| * To print the value with highest priority for key "foo.bAr Baz.rock": |
| * test-tool config get_value "foo.bAr Baz.rock" |
| * |
