+chessboard --- A package to print chessboards
+Version 1.5 Ulrike Fischer 2007
+
+CHANGES
+1.5: Corrected some bugs.
+     Added key getpiecelists.
+     Adapted the package to xskak.
+1.4: changed the code so that it work with xkeyval 2.5
+1.3a: corrected a small bug
+1.3:A lot of the pgf-code have been rewritten and extended.
+
+ATTENTION
+Upgrading to this version
+can change the look of existing documents.
+
+Notably two things can give problems: Since version 1.3 the value of the
+padding key affects much more objects (marks) in the pgf
+pictures. So it could be necessary to reset the padding. And the
+applycolor has changed its behaviour. It will now also affect
+the foreground picture.
+
+
+CONTENTS AND INSTALLATION
+
+- Readme (this file)
+- chessboard-scr.dtx
+- chessboard.ins
+- chessboard.pdf
+
+Run TeX/LaTeX on chessboard.ins to unpack the dtx.
+Put the four extracted files in tex/latex/chessboard/.
+
+The dtx-file doesn't contain any documentation.
+So running LaTeX on it makes no sense!
+
+Put chessboard.pdf in
+ doc/latex/chessboard/
+
+DOCUMENTATION
+
+chessboard.pdf. There isn't a source for the documentation as it use some
+local fonts and styles.
+
+DESCRIPTION
+
+This package offers commands to print chessboards. It can print partial boards,
+hide pieces and fields, color the boards and put various marks on the board.
+It has a lot of options to place pieces on the board. Using exotic pieces e.g. for
+fairy chess is possible.
+It can be used together with the newest version (1.4) of the skak package
+which you can find at CTAN and together with xskak. 
+
+
+REQUIREMENTS
+chessboard uses some primitives of e\TeX. It needs a recent version
+of chessfss and xkeyval. It also needs the packages xifthen,
+pgfcore and pgfbaseshapes (from the pgf bundle),
+and pst-node (from pstricks).
