[FWTools] which tool to replace ArcGIS feature to polygon function

[Stefan Muthers]

Hello,

sorry, I do not know where to post this question. Since fwtools include 
many free software GIS tools, maybe someone could help me.

I have polylines I want to convert to polygons. Each polygon has an 
attribute that is taken from a point object located in the polygon area.

Until now, I use ArcGIS feature to polygon function, which works quite 
well. Due the rest of the processing is automated and realised with free 
software I would like to replace this step.

Is there any free software tool with the functionality of the ArcGIS 
tool? The best think would be a python function.

thank you!

regards
   Stefan
