+ *
+ * This will not magically fix all modules. Special cases should be promisified
+ * manually.
+ *
+ * The second argument is a bag of options:
+ *
+ * - without: an array of function names that shouldn't be promisified
+ *
+ * - multiResult: an object whose keys are function names and values are lists
+ *   of parameter names. This is meant for functions that invoke their callbacks
+ *   with more than one result in separate parameters. The promisifed function
+ *   will return these results as a single object, with each result keyed under
+ *   the corresponding parameter name.
