Initial import of isakmpd, an IKE (ISAKMP/Oakley) implementation for the

OpenBSD IPSEC stack by me, Niklas Hallqvist and Niels Provos, funded by
Ericsson Radio Systems.  It is not yet complete or usable in a real scenario
but the missing pieces will soon be there.  The early commit is for people
who wants early access and who are not afraid of looking at source.
isakmpd interops with Cisco, Timestep, SSH & Pluto (Linux FreeS/WAN) so
far, so it is not that incomplete.  It is really mostly configuration that
is lacking.

+.Sh NAME
+.Nm isakmpd.conf
+.Nd Configuration file for isakmpd
+.Sh DESCRIPTION
+The
+.Nm isakmpd.conf
+is the configuration file for
+.Nm isakmpd
+daemon managing security association and key management for the
+.Nm IPSEC
+layer of the kernel's networking stack.
+.Pp
+The file is of a well known type of format called .INI style, named after
+the suffix used by an overrated windowing environment for its configuration
+files.  This format consists of sections, each beginning with a line looking
+like:
+.Bd -literal
+[Section name]
+.Ed
+Between the brackets is the name of the section following this section header.
+Inside a section many tag/value pairs can be stored, each one looking like:
+.Bd -literal
+Tag=Value
+.Ed
+If the value needs more space than fits on a single line it's possible to
+continue it on the next by ending the first with a backspace character
+immediately before the newline character.  This method can extend a value for
+an arbitrary amount of lines.
+.Pp
+Comments can be put anywhere in the file by using a hash mark, "#".  Then
+the comment goes on to the end of the line.
+.Pp
+.Sh EXAMPLE
+An example of a configuration file:
