Omission in lcb_touch man page?

Hi, https://github.com/couchbase/libcouchbase/blob/master/man/man3couchbase/lcb_touch.3couchbase.txt
seems to miss out completely the exptime parameter, the single parameter that this function seems to be about.
Or am I terribly wrong?

Kind regards,
Hans

Thanks for report. Fixed in http://review.couchbase.org/27718
