====== Original Knights Graphics, Sounds and Room Layouts ======

The original Amiga Knights was written by Kalle Marjola aka Reaper.
The sound effects were provided by Miku.

This version of Knights incorporates the graphics, sounds and room
layouts from the original Amiga game, which are available from the
following web site:
http://www.cs.helsinki.fi/u/marjola/games/design.shtml#knights

The Knights files have now been released under the GPL; see
amiga_knights/ks_disclaimer.txt for details.



====== Simple DirectMedia Layer (SDL) ======

This software includes a copy of the Simple DirectMedia Layer (SDL)
library. This is a cross-platform multimedia library, providing access
to graphics, sounds and so on. It is made available under the terms of
the GNU Lesser General Public Licence (LGPL), the full text of which
is included separately (see third_party_licences/LGPL.txt).

The latest version of SDL is always available from
http://www.libsdl.org/. 

(On the Windows version of Knights, you may upgrade to the latest
version of SDL by replacing the relevant DLLs in the Knights
directory.)



===== SDL_TTF and FreeType =====

This software uses SDL_TTF, which in turn uses FreeType, which is
copyright (C) 2007 The FreeType project (http://www.freetype.org/).
See third_party_licences/FTL.txt.

Note that I have included the SDL_TTF .c and .h files into the project
directly, rather than linking to them as an external library. (I have
also made a small modification to my copy of SDL_ttf.c, see
src/platform/SDL_ttf.c.) Please be aware of this if you are swapping
in a new version of SDL_TTF for any reason.



====== Guichan ======

The front end menus were created with Guichan, a free GUI library
available from http://guichan.sourceforge.net/. The following licence

implementation of) the Scale2x algorithm, developed by Andrea
Mazzoleni. See http://scale2x.sourceforge.net/.

====== Other Software Used ======

Various other programs were used to create this version of Knights.
Here is a list:


* The GOLD Parsing System
  http://www.devincook.com/goldparser/

  A free parser generator. I used this to create a parser for the
  Knights configuration files (examples can be found in the
  knights_data folder).

  Please note that I only used the main GOLD parser generator tool. I
  did not use any of the 'engines' available from the GOLD site -- I
  found the C++ ones to be somewhat unreliable, so I wrote my own!

  [Note this will likely disappear in a future release as I am
  switching to Lua for configuration files...]


* Inno Setup
  http://www.jrsoftware.org/isinfo.php

  This was used to create the Windows installer. (I find this a lot
  easier to use than NSIS, which is what I was originally using for
  installers.)


* ImageMagick
  http://www.imagemagick.org/

  The "convert" utility from this package was used for converting the
  graphics files from the original Amiga Knights.


* GIMP
  http://www.gimp.org/
 
  Image editing program.


* SOX
  http://sox.sourceforge.net/

  This was used to convert the original Amiga sound files to WAV
  format.


* SCons
  http://www.scons.org/

  A make replacement -- Describes itself as a "software construction
  tool".


* AMOS Professional 

  An Amiga programming language and development environment. This was
  used to develop the original Amiga Knights.


* Python 
  http://www.python.org/

  This was used for various purposes (e.g. to write scripts to convert
  the original Knights rooms data to a text file format).


* Emacs, for editing the source files


* GCC/G++, for compiling the code.


Development was done both on Linux and on Windows (the latter using
Cygwin and, more recently, Microsoft Visual C++ Express Edition).
