Comment (by mlennert):

 As much as I've found the file option for r.series et al very useful, I
 cannot say that I have been confronted with situations where I felt a need
 for your proposed approach. I definitely would not want it to replace the
 file option.

 If we go for such a parameter file, I would suggest to keep it very
 simple, i.e. one format, with my preference going to the one used in your
 example with a simple parameter=value pair per line, maybe with a special
 treatment of flags to create something like in the python parser, i.e.
 with the possibility to cite several flags at once:

 {{{
 [...]
 flags=ng
 }}}

 instead of


 {{{
 [...]
 -n
 -g
 }}}
