Provide a new comment tag to specify the summary of an API description.
By default, the summary of an API description is inferred from the first sentence, which is determined by using either a simple algorithm or java.text.BreakIterator. But, the heuristics are not always correct, and can lead to incorrect determination of the end of the first sentence. A new inline tag {@summary ...} is now available, to explicitly specify the text to be used as the summary of the API description. Please refer to Documentation Comment Specification for the Standard Doclet.
