In the index.html file, if you were to use ../ in the links for the Linux docs, instead of a file:/usr/doc/ URL, the file would still work for those at the console of the Linux machine. However, those of us who use Linux machines as servers would also be able to use the page. I place an alias in my Apache such as: Alias /rhl /usr/doc/ as a way to read the documentation via a web browser on another system. If the suggested alteration were made to the index.html file, that file would be useful as a top-level page even for setups like mine.
Thank you for your suggestion. It has been noted and will be passed on to a developer for further review.
Changed for next version. There are arguments both ways -- with the absolute paths, the document still works even if it is moved elsewhere in the file hierarchy. But I think that the arguments are stronger for relative paths, so I've changed it.
