[Gdal-dev] Clip shapefile into a polygon

["SAEZ Laurent - CETE Méditerr./DI/ETER"]

Hi,

First, I would like to apologise for my English... I hope someone will understand me.
I have many shapefiles representing contours of French departements.
I want to clip each of them using a polygon from another shapefile (the departemental borders).
I've tried to do that with ESRI products. Sometimes it's OK, but sometimes not.
Is there an utility program that allows to clip a shapefile with another one ?

Regards
