--exec which, I think, is successful since I can see it used in different
posts online. However, I also think that --exec is far from an ideal
interface. I seek comments for the ideas and newly proposed CLI and
potential Python API design which is presented at the wiki.

The example in the wiki is based on a GeoTIFF file with a single raster
band. IMHO, the input should be more general in the form
"GDAL_raster_datasource raster_band" and "GDAL_vector_datasource
layer_name". Specifying a raster band/layer name should probably be
mandatory. The new parser would then use GDAL to test if the given
datasource is valid and if the given raster band/vector layer exists in
this datasource.

I guess the main part of this project would be to write a parser for the
`grass run` arguments that translates them to an actual GRASS command.

I would be interested in the general design and concept for the
implementation of this project.

A very interesting idea that would facilitate the use of GRASS as a toolbox
similar to GDAL or (ambitious reference) OTB.

including those of you who posted on the mailing list so far to CC just to
let you know that you can apply for more than one idea which is more than
appropriate when there is more than one student interested in the same
idea. Please find details about this idea at the wiki.
