+/*
+ * 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 -> print return value for the entered key
+ *
+ * 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
+ *
+ * git_config_int -> iterate over all values using git_config() and print the
+ * integer value for the entered key or die
+ *
+ * Examples:
+ *
+ * To print the value with highest priority for key "foo.bAr Baz.rock":
+ * test-tool config get_value "foo.bAr Baz.rock"
+ *
