Thanks for the replies.
jfondren: Sorry, but I am talking about documentation. For me,
online web pages don't qualify; they are in the cloud, unreal,
with no substance. Does anyone really read 300 pages online, in
a web browser? Of course not.
Jordi Sayol: PDF! ePub! Now that's what I call documentation!
But that's on SourceForge. My first port of call to learn about
D was, and is, dlang.org, where the *only* links to the "D
Programming Language Specification" in any downloadable format
are for the Mobi.
