Bertrand '88 Beta distribution. The documentation has been converted from troff to html. See Documentation.html and Guide.html. The directory "libraries" contains the bertrand libraries, and the directory "examples" contains a small number of examples. Other examples can be typed in from the book. I'd appreciate copies of interesting programs that you write in Bertrand. The file graphics.h was generated automatically from graphics.cps by the program cps (which comes with the NeWS window system from Sun Microsystems). If you do not have NeWS, you will need to rewrite graphics.c and ignore graphics.h and graphics.cps. These files are pretty simple, actually. There is also graphicsnull.c, that simulates a graphics device but just prints out everything rather than drawing it. There is a Google Group for Bertrand. See http://groups.google.com/group/bertrand-constraint There is also a Git repository. See http://github.com/bertrand-constraint/ Talk to me to get commit permission. Have fun! Wm Leler
