Having hacked both MudOS and DGD reasonably deeply, I would be
careful about using an LPC reference that isn't DGD specific.
The differences in the approach of the two drivers, particularly
the kfun/efun/simul_efun concept, are large enough to confuse
even a moderately experienced wizard. Someone should write a
DGD-LPC document if it hasn't already been done.

A DGD kfun is probably more similar to a MudOS simul_efun than
to an efun, although the analogy's not perfect in either case.

If you're starting with a base lib such as Melville, then the
differences are pretty minor as far as the drivers are concerned.
If you're going to write your own auto object, though, then the
differences are severe. If you plan to code "from scratch", I'd
still recommend taking either the Melville lib or the kernel lib
and using its driver function, auto function, user and player
objects, and a few more. At least until you can hack up your
own versions.

Without using the MudOS to DGD package, porting would be more work
that rewriting from the basis of Melville or the kernel lib IMHO.
