/**
 * Annotation for method parameter declarations which denotes that actual parameters will be used as
 * a format string in printf-style formatting.
 *
 * This is an optional annotation used along with the {@link FormatMethod} annotation to denote
 * which parameter in a format method is the format string. All parameters after the format string
 * are assumed to be printf-style arguments for the format string. For example, the following
 * snippet declares that {@code logMessage} will be used as a format string with {@code args} passed
 * as arguments to the format string:
 *
 * 
{@code
 * public class Foo {
 *   @FormatMethod void doBarAndLogFailure(@FormatString String logMessage,
 *       Object... args) {...}
 * }
 * }
 *
 * See {@link FormatMethod} for more information.
