Why don't you rename to doc/KLIPS-IPv4-only/ ? If you do not want to update
the contents. What do you think package maintainers would do? They would
include the files anyway in the package and user will read them. Please
cleanup the files, delete what is not relevant to current, make some meaningful
hierarchy in the directory structure.

I tried in the night to compile KLIPS against the tree with no IPv6
configured and ended up with ipsec.ko and some kernel crashes afterwards.
Maybe I had to omit some IPsec stuff from the vanilla kernel? Will repeat that
and report in another thread, and lookup some current openswan docs how to
configure KLIPS (whatever that is). ;)
