[Dune-devel] Future of dune-grid-howto?

Dear Dune developers,
recently while testing new compilers and recent versions of CMake, I
stumbled on warnings in dune-grid-howto. The fix was quickly written,
but I found out that finitelements has never been working with CMake.
This remained unnoticed since the first CMake-related commits back in
2012!
In general, dune-grid-howto is poorly maintained, it lacks all the
cool features we introduces with free functions and for-range loops,
the purpose of the module is not clear and to me it seems that the
discretization modules (FEM, PDELab, DuMuX etc.) took over with direct
user contact.

I was asking myself a couple of questions and would like to hear what
others think:
* What is the purpose of dune-grid-howto today?
* What first impression does the module give to interested users?
* Why does virtually nobody of us care about it?
* Should we drop the module? What would we advice for new users instead?
* Can we overhaul and modernize it (do we have the resources, are we
willing to do so)?
* Can we drop the authors listed in the beginning of the document and
make it more vivid?
* Would a modernization be a good GSoC project?

Bye
Christoph

Unfortunately, plots are notoriously hard to get right. Partly, the
default settings of programs like gnuplot or Excel are to blame for
this since these programs make it very convenient to create bad plots.
