Man pages missing from libcouchbase

I installed libcouchbase using Ubuntu repository for 14.04 but man pages are missing. man libcouchbase says man page not found.

Developer manpages were removed in 2.4.0 and replaced by Doxygen-generated API documentation. You may find the latest version at http://docs.couchbase.com/ (in the Couchbase SDKs section, under ‘C | API Reference’)
