how do I scale a shapefile?

[Donal]

Just for the record, I think I have it with the following :

 ogr2ogr -s_srs ' +proj=tmerc +lat_0=33 +lon_0=129.5 +k=0.999900 +x_0=0
+y_0=0 +ellps=bessel +to_meter=0.001' -t_srs EPSG:30161 out.shp in.shp

and I got my settings by looking up the value for 30161 in the
/usr/local/share/proj/epsg file.
