I've added Steve's response to the Experimental Parrot Wiki http://www.vendian.org/parrot/wiki/
Which, of course, has a link to his Tinderbox summary. Hmm... perhaps a little tinderbox "weather report" line should appear on the wiki main page? There are also links to CVS histories, and LXR, and... lots of other things. It might also be useful to have a response for someone who asks "I am a tech writer who knows Perl and C. How can I help?". Mitchell
