Tim,

It is possible to list the particular layers (by their object class name)
at the end of the ogr2ogr command.  If no layer names are provided then all
layers are translated.

So, for instance:

   ogr2ogr -f KML ~/099.kml master.000 ROADWY RUNWAY RIVERS

The ogr2ogr documentation is available at:

   http://www.gdal.org/ogr2ogr.html

though I must concede it has grown pretty complex.

Best regards,
