.... relying on php is a bad idea is people want to view it on their pc, as I imagine the majority of gamers here don't use a php enabled server to view manuals.
Looks like we have a misunderstanding. I was suggesting that one person with a PHP-enabled PC (as I have) could run a PHP script which: walks the directory structure; copies CSS, JS & images to an output directory structure; and generates pages in the offline manual's wrapper and writes them to the appropriate place(s) in the output directory structure. Then: check results; if OK, ZIP and FTP to the site from which other RS enthusiasts can download.
