You know what would be awesome? If the HTML manpages generated by R were actually microformat-enabled HTML. I was just thinking about how it would be nice if you could identify example code and whatnot from the eventual help page. I wonder how scary that code is? IIRC the HTML generated by R's manpage generator was pretty much HTML3 (so not even easy to style) so it could be pretty scary. It may even be one of the Perl bits.
Okay, I need to get some sleep now.
