-this is the case. I'm perfectly happy for non-GPL'd software to refer
-to adns in its source code or executables (eg, dynamic linking).
-However, if you distribute adns yourself then whether a program which
-uses it needs also to be GPL'd depends on the interpretation of the
-`work as a whole' and `mere aggregation' parts of the GPL.
-
-Whether you are distributing a `work as a whole' might depend on many
-things, but they key one to me is what the appearance is to a user.
-If the user knows that they are getting a collection of software
-rather than a single product, then it's probably an aggregation which
-works together. So, you can distribute both your (i) non-GPLd program
-source and/or binaries and (ii) adns source code or even binaries
-(provided the adns source is available as per the GPL), eg from your
-website, provided the user can tell that these are separate works and
-can tell which parts are which.
-
-But, if you package your program and adns together so that the user is
-no longer aware of adns as a separate work, then I think you are
-distributing a `work as a whole', and the whole work including adns
-and your software which depends on it must be GPL'd. This is of
-course not a problem if your non-GPL licence is GPL-compatible (see
-the next section): it just means that _when the whole lot is shipped
-together as one work_ it is covered by the GPL. People who wish to
-make proprietary works based on just your code can do so, provided
-they (or you) arrange for something to fill the hole left by the lack
-of adns.

-3. GPL-incompatible free software licences
-------------------------------------------
-
-Regrettably, there are a number of free software licences (and
-semi-free licences) in existence which are not compatible with the
-GPL. That is, they impose restrictions which are not present in the
-GPL, and therefore distributing a whole work which contains such a
-program and a GPL'd program is not possible: either the work would
-have to be distributed under the GPL (violating the restrictions made
-by the original author), or under the GPL-incompatible licence
-(violating the GPL).
-
-I may be prepared to make exceptions for such a licence. Please
-contact me at <adns-maint@chiark.greenend.org.uk> with the full text
-of the GPL-incompatible licence. However, I would prefer it if you
-could use a GPL-compatible licence for your project instead.
-
-There are a couple of common extra restrictions, and I make some
-specific extensions to my licence for adns below.
-
-3.1. BSD advertising clause and endorsement restriction
-
-The most notable and common extra restriction found in free software
-licences is the `obnoxious BSD advertising clause' (see Richard
-Stallman's article on the subject, available from www.gnu.org) and the
-endorsement restriction.
-
-The problem with the advertising clause isn't that the sentence
-required, referring the the Regents of the UC Berkeley, is awkward.
-The problem is that if everyone contributing to a large project gets
-such a mention the number of sentences required becomes very large;
-however, it is unfair for some people to get credit and others not to.
-
-I disapprove of these clause, but I recognise that it may be difficult
-for some people to get them removed from particular programs.
-
-So, I hereby make an extension to my licence for adns:
-
- You may alternatively distribute adns under the GNU GPL version 2
- with the following banner and either one or both of the following
- additional restrictions, to be inserted at the end of section 1:
-
- ADDITIONAL RESTRICTIONS:
- (The permissions granted in this licence only apply if you comply
- with the following restrictions:)
-
- (a) All advertising materials mentioning features or use of the Program
- (or a work based on the Program, GPL section 2) must display the
- following acknowledgement for each author, copyright holder or
- group of authors or copyright holders:
-
- This product includes software developed by PERSON OR GROUP.
+this is the case. I'm perfectly happy for non-GPL'd but
+GPL-compatible software to refer to adns in its source code. However,
+I think that exectuables (or compiled libraries) which contain or are
+dynamically linked against adns must be GPL'd; likewise executable
+programs (whether compiled or in an interpreted language) which
+require utilities from adns to function properly must be GPL'd.
+
+So, you can distribute your non-GPL'd program source which needs adns
+to compile (provided it's under a GPL-compatible licence), but people
+who wish to distribute binaries must do so under the terms of the GNU
+GPL. This may make sense for some GPL-avoiding free software
+projects; people can still make proprietary programs from your code,
+provided that they make some provision to replace adns with something
+whose copyright allows proprietary versions.
+
+However, this doesn't make much sense for the authors of LGPL'd
+libraries. All I can say to them is to ask which is more important:
+that their library be well-constructed and use all the best technology
+available as free software, or whether it is worth degrading quality
+of their library in order to allow proprietary programs to use it !
+
+To help the case of LGPL'd libraries for which adns is not a vital
+component - for example, a library which provides access to other
+libraries so that programs which use it need only use certain parts,
+I have released adns.h (just the public header file) under the LGPL as
+well as the GPL. See the copyright notice in adns.h for details.
+Note that this will not help you if it adns is essential to the
+functioning of your library, because all programs using your library
+must link against both your library and adns and so must be GPL'd.
