From W3C's HTML validator (build/index.html):
Error: Line 167:21: Duplicate ID title.
Error: Line 168:22: Duplicate ID author.
Warning: Line 106:20: The first occurrence of ID title was here.
Warning: Line 107:21: The first occurrence of ID author was here.
The second part is easy to fix - has to do with a diblicate ID: #author and #title - I guess fixing that - and then putting the rest in FUTURE will do
Fixed compiler warnings (re issue #83)
Deleted some old files (re issue #83)
I have not touched the HTML warnings, though.
I have created issue #446 to address the html issues and will close this one now.
