This new folder is supposed to solve
#1330.
Important: I unzipped the .zip file into a folder that I created, called asciidoc3. If I hadn't created that folder, unzipping would have spewed files all over my desktop!
As mentioned in #1330, it's possible to import asciidoc3 from that folder. Actually using the contents of the folder is another matter. I'll look into this briefly today. I would appreciate any help from other interested people.
