I've downloaded an e00 file with the outline from Laos. Import worked finally an I get it displayed as it should be. But now I wanted to export the map to an dxf file so that I can add some labels and fill the outline with a color. But when I import the dxf to corel draw it is composed of line segments (72 pieces) and I can't group them so that a filling of the area is possible. I think one problem is that the direction of the lines is not always in the same direction. So here my questions:
- how can I alter the vector file in grass so that I get a closed outline?
- is there an other resource of country boundaries which is more easily usable?
- what software would you reccomend to draw simple maps (boundary outline, different locations marked by symbols and some text needs to be added as well)?
- is there a GUI-viewer/editor for the database files available (at the moment I use the standard dbf files)?

If you need to connect nodes, use v.clean tool=snap. To build a
polyline out of connected lines, use v.build.polyline.
- is there an other resource of country boundaries which is more

vmap0? See in fregis list archives for somebody's ftp server with vmap0
already converted from it's native format to shapefile (few months
ago). I think I heard there's a new vmap0 release available, but
propably only native format (a bit tough, yet convertable, find hints
in the Grass lists archives and in Grass news pdf, by Markus Neteler).

QGIS? If you are interested only in vectors, then export from QGIS map
composer as SVG and edit further in Inkscape for a more fancy result.

For sqlite there is sqlitebrowser. Postgres and Mysql have some GUI user
iterfaces too, but I don't know details.

v.clean did the job. But I will also check out the vmap0 source.
