Split the pcap(3) man page into a bunch of individual man pages for
functions plus an overall man page for libpcap, and put them all into section 3PCAP. That means you can actually do "man pcap_open_live" and get something meaningful, rather than having to do "man pcap" and then scroll through all the other stuff in the man page.
