+== How can I delete feature from Shapefile? ==
+
+This question was asked a few times on the mailing list, for instance [http://lists.osgeo.org/pipermail/gdal-dev/2007-March/011992.html here] and [http://lists.osgeo.org/pipermail/gdal-dev/2007-March/012109.html here]. It's recommended to look at these threads as they provide explanation on how to delete entries from [http://gdal.org/ogr/drv_shapefile.html Shapefile].
+
+It is not possible to delete features from Shapefile using [http://gdal.org/ogr2ogr.html ogr2ogr] utility.
+
+In order to remove entries from Shapefile, you need to call [http://gdal.org/ogr/classOGRLayer.html OGRLayer::DeleteFeature()] method, either directly from C++ program or using one of alternative interface like [http://gdal.org/ogr/ogr__api_8h.html OGR C API] or [http://trac.osgeo.org/gdal/#GDALOGRInOtherLanguages bindings to other programming languages].

 Here's a bash script to bulk load a directory of shapefiles that have the same schema to postgis.  It could obviously be made smarter, but it seems to do the trick.
