I commented earlier on Activestate's HTML Documentation. I have Build 629 installed on my pc. I installed a more recent version on a friends pc and was dismayed to realize that they switched the HTML documentation from a large group of HTML files to a single .chm(compiled HTML) file. This might be a resonable move for some applications, but it does not work well with perl where new modules need to be added to the core distro. The old way, new package downloads would add HTML docs to a table of contents and make life easy, now you have to hunt through the directory tree. Anyway you can still download the old style documentation with a ppm command, But I wish that they didn't add this "improvement" by default.
