/**
 * If this annotation is attached to a {@link Formatter#format}-like method,
 * then when type-checking calls to the method, it will be a candidate method
 * checked by {@link FormatStringChecker}.
 *
 * The first argument must be of type {@link Locale} or {@link String}.
 * If the first argument is of type {@code Locale}, the second argument must be of type {@code String}.
 * The String argument is treated as a format string containing zero or more embedded
 * format specifiers. The format specifiers determine how the remaining arguments will
 * be used within the resulting output.
 *
 * The {@code FormatStringChecker} ensures that the format string is valid and the
 * remaining arguments are compatible with the embedded format specifiers.
