Read any markdown file for index.html

I think it would be nice to be able to read any markdown file.

from README.md to anyfilename.md

Yeah. I'm planning to move in this direction.

But my idea is to turn yourfile.md into yourfile.html. Except for README.md which I'll currently need to transform into index.html for backwards compatibility.

I think I was thinking the same thing. I was thinking transform *.md > index.html.

I've now implemented what I described in earlier comment.
