- It's mostly about file structure/organization (duh)

- It also contains slightly deeper links, e.g. about on what objects
  other things are defined.

- In the end it's all about links. There are some data properties but
  they are honestly not that interesting. They are necessary for
  lookup however.

I like playing w/ languages, but I am not sure at all if this is a
good idea.

First draft; will be revised.

- code goes into /src

- prose in /doc

- /experimental is a playground
