More feature additions

13 Apr 2013

      "unlang" has now been updated to use the new update parsing Arran
added for the LDAP and cache modules.  This makes the update sections a
little simpler, with a bit more power.

  You can now use attribute references.  For clarity, they require the
use of "&":

	update reply {
		Filter-Id := &request:User-Name
	}

  This copies User-Name from the request to the Filter-Id in the reply.
 The value isn't printed, expanded, or parsed.  it's a straight copy of
internal data structures.

  You can also do:

	update {
		reply:Filter-Id := &request:User-Name
	}

  Which does what you expect.

  The following is likely to *not* work:

	update {
		reply:Filter-Id := "foo"
		request:User-Name := "bar"
	}

  That should probably work in the future.  But not now.

  The old format for the "update" sections is still accepted, and still
works.

  The current status of v3 is that it has had a number of old and unused
modules deleted.  However, it has about the same number of lines of code
as v2.2.0, and has a fair bit more functionality.  It's good to see that
the server is being simplified while it's being made more complex. :)
