 Sieves [GeoPackage](https://www.geopackage.org/) Polygon geometries.
 
 The purpose of this application is to prerefine the (MULTI)POLYGON geometries in

+vector tiles can be omitted, and less data needs to be processed.
 
 ## Notes
 
 - It will take a Geopackage and writes a new Geopackage where all the
-  (MULTI)POLYGON tables are sieve.
-  - All other geometry tables are 'untouched' and copied as-is.
-  - Other none geometry tables are not copied to the new geopackage.

+  - Other not spatial tables are not copied to the new geopackage.
 - The area of a POLYGON is used for determining if the geometries will be
   sieved, not the extent. So geometries with a extent larger then the given
-  resolution but with a area smaller then that resolution will be sieved.
