Maybe I am missing, but I do not see any index file when html files are generated by ddoc. Is there any way to generate index file automatically, so, a tree like links will be listed all created documentation files?

If the problem is about the possibility of having index.d and it would be confused with index.html, I can understand.

I'm not sure if you can do this only using dmd.
I recommend the ddox generator / server. Martin Nowak made a nice theme for it:
