Since 2.10.0, HTML help is generated on demand. It doesn't go off your
local computer, it works locally. This saves a bit of space (the HTML
is generated from the same source as the text is generated from), but
the main point is that it allows help pages to contain dynamic content.
For example, Romain Francois posted some demo code a while ago to allow
the display of graphics generated by R within help pages.
(Unfortunately it depended on a particular browser feature not supported
by Internet Explorer, so I'm going to need to put together something
less elegant, but that's life.)
