Someone recently wrote me, asking for the old CodeView format. I told him that it was readily available on the web. He subsequently wrote back and said he couldn’t find them.
So, using both MSN Search and Google, I dug around and was able to find the spec, but in only one place. And I only found it because I knew lots of key words in the spec that the average person wouldn’t.
So, for posterity’s sake, here are two useful links:
