I'll try to get around to it Real Soon Now, but it takes just about 1/2 hour of free time to write such a document, and I haven't found that many free half hours during the last months (I started this stuff in July 1995!)
If you want to contribute text, that's helpful - I'll mangle it three ways from Thursday, but contributing text is a very useful way of getting me to write something!
Enjoy, and have patience!
