Where did the specification ebook go?

[Jakob Ovrum]

There is a link to a file `dlangspec.mobi` on this page:

     http://dlang.org/spec.html

The ebook link is dead. I tried building an ebook myself using 
the makefile, but to no avail; kindlegen encountered dozens of 
problems with the generated dlangspec.html.

Anyway, spec.html is not even reachable through any links on the 
site as far as I can tell. Shouldn't "Language Reference" in the 
sidebar link to that page? It currently sends you to lex.html. 
"Library Reference" links to an (incomplete!) overview of Phobos; 
it's probably a good idea to have the two links behave the same, 
even if that means "Library Reference" linking to, say, 
/phobos/object.html.

I see that there is also an ebook sold on Amazon linked from that 
page; not sure what I think about monetizing an open source site 
like that, even if the copyrights of contributors are technically 
yielded to Walter. I'm thinking there might be some good reason 
here, though.

By the way, why does the makefile look for \kindlegen\kindlegen 
by default? For one, those are Windows specific path separators, 
and shouldn't it look for just "kindlegen" in the PATH 
environment variable?
