Hi Hidemote, 

I'd like to understand the purpose of the config file
better, so I have a couple of questions.   I found the
config-file section in the Ninf-G user manual.

What is the general idea of the config file?  To me it
sounds like it configures the (client side) backend, not the
API - would that not better be hidden in some ~/.ninfgrc or
so?  

Are there many values which are intended to change from one
application run to the next?

The GridSolve user guide is silent about the config file
structure - is it the same as in Ninf-G?  

If not, how does GridSolve handle the client side
configuration?

We write the reference implementation in C++ - so its even
simplier I think :-)

Cheers, Andre.
