+/**
+ * An entry contains all meta information for a configuration.
+ *
+ * @param key the key for the configuration
+ * @param defaultValue the default value for the configuration
+ * @param valueConverter how to convert a string to the value. It should
throw an exception if the
+ * string does not have the required format.
+ * @param stringConverter how to convert a value to a string that the user
can use it as a valid
+ * string value. It's usually `toString`. But
sometimes, a custom converter
+ * is necessary. E.g., if T is List[String], `a, b,
c` is better than
+ * `List(a, b, c)`.
+ * @param doc the document for the configuration
