libcasper.3 has a .Xr cap_gethostbyaddr 3 but the target page does not exist; in fact documentation is missing for all of the services AFAICT (cap_dns, cap_grp, cap_pwd, cap_random, cap_sysctl, cap_syslog).
Hey Ed, Did you look on head or on release? From the beginning of the year I was adding some man pages to Casper. Currently missing ones are: cap_pwd and cap_sysctl
Indeed, I'm sorry - I had a slightly out-of-date tree.
