sorry, I saw in http://hub.qgis.org/issues/4667
and just saw the 'trunk' when running 'locate' but not the source tree
it came from (qgis's).
so those are GRASS python scripts in qgis svn written by Radim which
use the GRASS python libraries. hopefully with 6.4.2 'import from grass'
will be a lot more stable, in the past few releases it was still under-
going some new development. But that still will be very new and will
probably continue to change a little.
note that grass scripts (both python and shell scripts) need to be in
the system PATH to work correctly.

my thinking was that many grass devs probably can not keep up with the
qgis-dev mailing list traffic, and many qgis devs probably can not keep
up with the grass-dev ML traffic. so if there was a low volume ML for
interested parties from both dev teams it would be easier to keep up

command line interfaces should not have changed at all since GRASS 6.0.0
in March 2005. the goal has always been that any command (script) written
for GRASS 6.x will be forward-compatible with any future GRASS 6.x ver.
The C API has changed a little with time :-(, but I don't think you use
that? In the case that it does change, the module should bomb out with
a GIS_H API mismatch error.
The python API is still being developed, so no guarantees of stability
it is hard to predict unintended consequences, but we do our best..
