I want this info in the kernel. At the very least, I want
documentation as a part of the SYSCTL_*() macro parameters, unused but
available as a (mandatory) part of the source - better would be as a
part of the kernel that can be compiled away by setting a kernel
option (e.g. NO_SYSCTL_DOCS).
Would you buy it in /usr/share/misc/sysctl_nodes? I was thinking about
that when I saved John's message...
