Trying to debug Hugo and my site

gistfile1.txt

Rendering blog.koehntopp.info now takes 400s in Jekyll. That's too slow.

I can import the entire thing into hugo with `hugo import jekyll ~/Source/isotopp.github.io isotopp` 
and get a hugo version of all.

That leaves me with the work to port Type-on-Strap to Hugo. But I do not 
even understand how Hugo applies Templates and it is hard to debug.

So this leaves me with some output.

With my template

Now I wonder where my baseof.html and stuff is, and if there is a way to see what
Hugo considers, but does not use and why.
