== Directly showing attached code files
Testing reveals that this already works with the recent Moinmoin 1.9
release. (We are still running an old version.)

When using something like 
  {{attachment:example1.py}}
it will be shown with syntax highlighting.

== Choosing the way forward
Ralf, why do you prefer SF wiki in particular?

There really is a medium sized kind of work to transfer the markup
and it would be missing features like subpages and directly showing attached
code files.

To me the transfer work is an argument, as we probably will still have
to clean up. We could go to waldmann-edv and later still switch to
somewhere else
if Intevation would stop paying for it in the future. Right now this seems
to be less work for core roundup devs.
