Netbeans plugin and Python 3

Hi,
I never tried python3.0 with netbeans but I use python 2.6.5 with netbean
6.7.1
Here is how I managed to change from python 2.5 (netbeans default) to 2.6.5
1) From the tools-> plugins section install python plugin
2) Once plugin is installed just restart netbeans so that plugin is
activated
3) After plugin is activated, you can edit default python version by tools->
python platform
4) It will open a configure window, where you can point python to newly
installed 3.0 version.
I hope that helps.
Thanks,
nitin
