Poul-Henning Kamp 19c749625f Initial entry of ISDN4BSD into the FreeBSD tree.
ISDN4BSD is the work of our brand-new comitter: Hellmuth Michaelis,
who has done a tremendous amount of work to bring us this far.

There are still some outstanding issues and files to bring into
the tree, and for now it will be needed to pick up all the extra
docs from the isdn4bsd release.

It is probably also a very good idea to subscribe to the isdn@freebsd.org
mailing list before you try this out.

These files correspond to release "beta Version 0.70.00 / December
1998" from Hellmuth.
