This is a job for the GRASS Extensions Manager (GEM), see gem/README in the GRASS 6.2.2 or 6.3 source code, and one of the reasons it was written. Note that some developers may not be terribly interested in devoting their own volunteer development time into coding a "tivo" solution that makes it easy to sidestep the spirit of the GPL. The more that happens, the less chance of a true "Open" DWG library ever gets written for OGR/GDAL. This is not anti-user elitism, it is supporting long term user interests over short term band-aids. > i'd be happy to provide the library code to developer(s) to update > v.in.dwg; it would be a collaborative partnership with our organization, > thus within the legal constraints of the license. if this is a real > possibility, whom would i contact? Contact this mailing list (grass-dev). Patches can go into the GRASS patch tracker, and are most welcome. It helps if you can convince a member of the development team to become interested in it.
