Such an "online book" could deal with versioning issues quite
nicely.
If a specialized book writing site isn't available then I'm
sure a
wiki would work.
http://wiki.dlang.org/
;-)
Seriously, though, the wiki could use someone who could
dedicate some
love and care to it, to get it into a shape that's readily
accessible
for newcomers. There's already a section devoted to D-related
articles
and a tutorial section with a number of "best practices"
articles, but
it's still rather bare and needs more content -- a *lot* more
content.
T
snap! :)
