[geotk] First try with geo-tk. Display a map with Shapefile

[Martin Desruisseaux]

Hello Arnaud

Johann is in better position than me for answering your question. Right now he 
is in a rush because of the FOSS4G event which is hapenning this week. But I 
guess that during the next week things will calm down a bit...

     Regards,

         Martin
