> WARCExporter is a handy tool to dump the segments. Unfortunately it also emits WARC records for status' other than success of notmodified, which accounts for a decent number in each crawl cycle. It also doesn't emit parsed metadata or extracted text. It does now.
>  
> This patch adds three switches:
>  * -includeOnlySuccessfulResponses to only emit records of success or notmodified
>  * -includeParseData to also emit parse metadata as WARC metadata record
>  * -includeParseText to also emit extracted text as WARC metadata
> Both metadata objects are stored in the same WARC metadata record to save space.
