21  *  For the benefit of certain LGPL'd `omnibus' software which provides
22  *  a uniform interface to various things including adns, I make the
23  *  following additional licence.  I do this because the GPL would
24  *  otherwise force either the omnibus software to be GPL'd or for the
25  *  adns-using part to be distributed separately.
26  *
27  *  So, you may also redistribute and/or modify adns.h (but only the
28  *  public header file adns.h and not any other part of adns) under the
29  *  terms of the GNU Library General Public License as published by the
30  *  Free Software Foundation; either version 2 of the License, or (at
31  *  your option) any later version.
32  *
33  *  Note that adns itself is GPL'd.  Authors of adns-using applications
34  *  with GPL-incompatible licences, and people who distribute adns with
35  *  applications where the whole distribution is not GPL'd, are still
36  *  likely to be in violation of the GPL.  Anyone who wants to do this
37  *  should contact Ian Jackson.  Please note that to avoid encouraging
38  *  people to infringe the GPL as it applies the body of adns, Ian thinks
39  *  that if you take advantage of the special exception to redistribute
40  *  just adns.h under the LGPL, you should retain this paragraph in its
41  *  place in the appropriate copyright statements.
