+/**
+ * HttpException and its subclasses provides exceptions that correspond to HTTP
+ * error status codes. The most common are included, but you may create
+ * additional subclasses if needed by subclassing HttpException.
+ *
+ * The HttpException classes are intended to be used with Handler subclasses
+ * (pjdietz\WellRESTed\Handler). Handler::getResponse() catches HttpException
+ * exceptions and converts them to responses using the exception's code as the
+ * HTTP status code and the exception's message as the response body.
