23 <p>XBoard is a graphical user interface for chess in all its major
24 forms, including international chess, xiangqi (Chinese chess) and
25 shogi (Japanese chess), in addition to many minor variants such as
26 Losers Chess, Crazyhouse, Chess960 and Capabanca Chess. It displays a
27 chessboard on the screen, accepts moves made with the mouse, and loads
28 and saves games in Portable Game Notation (PGN). It serves as a
29 front-end for many different chess services, including:</p>
32 Chess engines that will run on your machine and play a game against
33 you or help you analyze, such as GNU Chess, Crafty, or many
36 <li>Chess servers on the Internet, where you can connect to play chess
37 with people from all over the world, watch other users play, or just
38 hang out and chat.</li>
40 <li>Correspondence chess played by electronic mail. The CMail program
41 automates the tasks of parsing email from your opponent, playing his
42 moves out on your board, and mailing your reply move after you've
45 <p>XBoard runs on Unix and Unix-like systems that use the X Window
50 <p>The project also includes a port to 32-bit Windows systems called
53 <p>You can find the download section for Winboard at
54 the <a href="http://www.open-aurec.com/wbforum/viewforum.php?f=19">Winboard
57 <p>Development for Winboard, reporting bugs and any other requests can
58 also be done at the same places as for XBoard (see below).</p>
60 <h3>Downloading XBoard</h3>
62 <h4>stable version</h4>
64 <p>The current stable version
65 is: <a href="ftp://ftp.gnu.org/gnu/xboard/">4.4.2</a></p>
67 <p>It can be found on the main GNU ftp server:
68 <a href="http://ftp.gnu.org/gnu/xboard/">http://ftp.gnu.org/gnu/xboard/</a> (via http) and
69 <a href="ftp://ftp.gnu.org/gnu/xboard/">ftp://ftp.gnu.org/gnu/xboard/</a> (via ftp).</p>
71 <p>It can also be found on one of the <a href="/prep/ftp.html">mirrors
73 please <a href="http://ftpmirror.gnu.org/xboard">use a mirror</a> if
76 <h4>development version</h4>
78 <p>It would be great if people would like help in the developing process. We can use all kind of help, from people who just use the software and have a feature request (send them to developer mailing list), to people who can update/check the documentation and especially people who test development versions (send problems to the developer mailing list). </p>
80 <p>At the moment we have three developer versions:</p>
83 <li>A snapshot of the 4.4.3 branch:
84 This will become the next stable version. <a href="ftp://alpha.gnu.org/gnu/xboard/">4.4.3.20100118</a></li>
85 <li>A snapshot of the master branch: <a href="ftp://alpha.gnu.org/gnu/xboard/">master-20100118</a>. <br />
86 The master branch at this moment also includes changes that will go in future version, but not necessary in the next release. Since this includes lots of changes, chances for major bugs are higher.</li>
87 <li>A snapshot of the gtk branch: <a href="ftp://alpha.gnu.org/gnu/xboard/">gtk-20100118</a>. <br />
88 In the gtk branch we are working on merging Winboard and Xboard back together using a gtk-frontend. This code doesn't work 100% yet, it will crash quite often, but you can almost play normal games against a machine already.</li>
91 <h5>How to build the development version</h5>
94 <p> After cloning the git-repository, do ./autogen.sh, ./configure and then a make.</p>
97 <p> Unpack the tar ball and do ./configure followed by make.</p>
100 <p>For development sources and other information, please see
101 the <a href="http://savannah.gnu.org/projects/xboard/">XBoard project
102 page</a> at <a href="http://savannah.gnu.org">savannah.gnu.org</a>.</p>
104 <p>A snapshot of the latest source code for all branches is available at
105 the <a href="http://git.savannah.gnu.org/cgit/xboard.git">git
106 repository</a> on Savannah.</p>
110 <p>You can also find an archive of old versions on <a href="ftp://ftp.gnu.org/old-gnu/xboard/">the ftp server</a>.</p>
112 <h3>Documentation</h3>
114 <p><a href="manual/">Documentation for XBoard</a> is available online,
115 as is <a href="/manual/">documentation for most GNU software</a>. You
116 may also find more information about XBoard by
117 running <em>info xboard</em> or <em>man xboard</em>, or by
118 looking at <em>/usr/doc/xboard/</em>,
119 <em>/usr/local/doc/xboard/</em>, or similar directories on your system.</p>

138 <li> XBoard can also run engines that use the UCI protocol, with
139 the aid of the Polyglot protocol adapter. A new Polyglot
140 version, (1.4.30b), especially adapted to support the new
141 features of XBoard 4.4.0, can be
142 found <a href="http://alpha.uhasselt.be/Research/Algebra/Toga/polyglot-release/">here</a>.</li>
