Instructions on how to install the chess fonts can be found in the file chess12/INSTALLATION. The file chessdiag.mf allows to create the ``Mate in three'' problem in a separate window if your version of METAFONT supports it (it should do that!). There are two versions of this file: chessdiag.mf chessdiag.Xmf The last one can be used to draw the board in a X-window. Here is how: - setenv DISPLAY your_server:0 - mf "\mode:=localfont; mag:=magstep(0); screenchars; input chessdiag.Xmf" Oct. 1991 Piet Tutelaers (rcpt@urc.tue.nl)
