Haven & Hearth Client -- Copying Rights

This file documents the copying rights of the Haven & Hearth client
source tree. The source tree is partitioned into a few sections, each
with their own copying restrictions. These partitions and their
respective licensing details are as follows:

 * The files in the `src/haven' directory and its subdirectories are
   the main source code of the client. It is subject to the GNU Lesser
   General Public License, version 3, as published by the Free
   Software Foundation. A copy of this license can be found in the
   file `doc/LGPL-3' in this source tree. The copyright to all these
   files is owned by Fredrik Tolf and Björn Johannessen.

 * The files in the `lib' directory are external libraries and are,
   thus, owned by third parties. All the files mentioned in the
   `lib/ext' subdirectory are not actually distributed with this
   source tree, but are donwloaded externally as part of the initial
   build process. The owners and licenses of these files are as
   follows:
   
    - lib/ext/jogl/:
      The files in this subdirectory are part of JOGL, the Java OpenGL
      implementation. They are not compiled into the client binary,
      but just included for the compilation classpath.
      
      They are, as far as I can tell, co-owned by Sun Microsystems and
      the JogAmp community, and licensed under a BSD license. Please
      see its homepage, <http://jogamp.org/>, for further and current
      details.
      
    - lib/jglob.jar:
      This is a simple annotation processor for collecting various
      type lists in the source code. It was written by me, Fredrik
      Tolf, and can be considered to be in the public domain. Source
      code can be had at
      <http://www.dolda2000.com/gitweb/?p=jglob.git>.

    - lib/ext/builtin-res.jar, lib/ext/hafen-res.jar:
      These files contain varios data files with game content that are
      not downloaded on-demand by the client from the website. In
      particular, hafen-res.jar merely contains pre-downloaded copies
      of some resources to avoid on-demand loading of files that are
      almost certain to be needed, whereas builtin-res.jar contains
      files that are used internally by the client and therefore needed
      for "bootstrapping" the client. As such, hafen-res.jar could be
      completely removed with only potential loss of performance
      (rather than functionality), while as for builtin-res.jar, the
      client would either have to be modified to not need it, or the
      graphics in it would have to be replaced in order to run without
      its more stringently licensed contents.

      Their contents are owned by us, Fredrik Tolf and Björn
      Johannessen, and we reserve all rights to them.

 * The files in the `src/com/jcraft' directory are part of JCraft's
   open source implementation of the OGG and Vorbis multimedia
   formats. They have been extracted into the source tree to support
   some local modifications.

   They are licensed under the LPGL, version 2.1, and appear to be
   owned by JCraft, Inc. Its homepage is
   <http://www.jcraft.com/jorbis/>.

 * The files in the `src/dolda/xiphutil' directory are files
   constituting a simple library for actually using JCraft's
   Jogg/Jorbis libraries. It was written by me, Fredrik Tolf, and can
   be considered to be in the public domain.

 * The file `etc/icon.png' is the icon used for the main client
   window. You're perfectly free to copy it verbatim or replace it as
   you wish, but it should be considered our trademark.

 * The majority of the other files, including the Ant build file
   (`build.xml') and the various small scripts and insignificant data
   files in the `etc' directory (except `etc/icon.png', as described
   above) can be considered to be in the public domain.

 * The build script, when run by Ant, will produce lots of stuff in
   the `build' directory. It comes from all over the source tree, and
   will thus be subject to various of the above licenses. Particularly
   worthy of notice, however, is the `build/hafen.jar' file, which is
   the build script's primary output. It will consist of files
   compiled from the `src' directory, some resources from the `etc'
   directory (including our amazing trademark icon), and the extracted
   JCraft files. Thus, excepting our trademark, award-winning icon, it
   will be LPGL and a little bit public domain. Then, obviously,
   you're basically free to do whatever you like with it as long as
   you make sure to distribute the corresponding source code (and
   remember to honor our acclaimed, trademark icon).

It must be noticed that the Git repository which is the main keeper of
this source tree contains, in historical versions, copies of the game
resources (this was before the file `hafen-res.jar' existed). In these
versions, they are located in a directory named `res'. They are
subject to the same terms as `lib/ext/hafen-res.jar' as described
above. You are free to copy them around verbatim as part of the Git
repository. If, for any reason, you decide to publish a historical
version of this source tree which contains these resources, or any
derivative work thereof, you must add a notice pointing this fact out,
and the fact that they are owned by Fredrik Tolf and Björn
Johannessen, and are proprietary to us.

If you change the source code so as to incorporate other files of new
ownership or other licenses (like your own stuff), you should remember
to update this file accordingly, so as to not confuse any new
recipients.

Do notice, however, that if you wish us to incorporate any changes you
make into our mainline client, as published on Haven's & Hearth's
website, we will require you to turn over the copyright ownership to
us. Please see the README for details (the "Contributing back" section).
