The AOL folks shut down the old site without first creating a replacement. Maybe one day in the future the documentation will be readable on-line at SourceForge - that is probably their intent. In the meantime, you can either download the documentation tarball, unzip it, and host it for yourself locally, or use this site a helpful community member set up for the rest of us to use:
