Did you read dgd/mud/doc/kernel/overview that I quoted from or did you
unpack the DGD package and figured you'd start coding?

If you read it, perhaps you should reread this part:

  ---------------------------------------------------------------------------
  9. Extending the kernel library

  The kernel library was written in such a way that it can easily be extended
  without modifying any kernel objects.  The user manager and driver object
  contain hooks that allow routing of some calls to different objects.

  installed using "/kernel/sys/userd"->set_telnet_manager(obj).  Finally,
  create /usr/System/initd.c which handles system-specific initialization
  (for instance, the telnet connection manager must be installed from its
  create() function).
  ---------------------------------------------------------------------------

The first paragraph of the quoted bit is essential when dealing with
the kernel-lib, as just about everything has been set up so that you
can inherit and customize the functionality to your own liking.

If you haven't read the entire document yet, do yourself a favour and
take a few minutes to do so now. :-)

Regards,

Erwin.
