/*
 * 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"
 *
