Hi Jay - thanks for the link to the source - I will look into it and warp my brain ;) Thanks, yinso <div>On 4/30/07, Jay McCarthy <<a href="mailto:jay.mccarthy@gmail.com"> jay.mccarthy@gmail.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I can comment briefly. The paper <<a href="http://www.ccs.neu.edu/scheme/pubs/icfp05-pcmkf.pdf"> http://www.ccs.neu.edu/scheme/pubs/icfp05-pcmkf.pdf</a>> has been implemented, by Greg Pettyjohn. It is available as `prototype-web-server' in the `graveyard' section of the SVN repository. I have recently rescued it from bit-rot and wrote a useful application in the input language it requires. After the next release, I plan on making that available in the mainline web-server and gradually improving its coverage of the language. But, I am doing this to scratch an itch, rather than produce research or bullet-proof products. Jay </blockquote></div>
