Thanks Hamish for the report.
The Doku had indeed to be updated.
Regarding to the SWIG bindings there are two major problems.
1) the license would not permit us to be LGPL. JGrass only executes GRASS
applications, without touching their code.
2) We have no resources right now to create the bindings, even if as you
mention, being there already well done binding for other languages, the
efforth would be reduced.
