[GRASS-dev] Discussing new GUI toolkit: v.pydigit

[Jachym Cepicky]

Hallo,

I created new site, where actual versions will be stored

    http://les-ejk.cz/?cat=vpydigit

Currently version

    http://les-ejk.cz/programs/grass/v.pydigit-06-05-31-1.tgz


BUGS: 
    * Some point data are not read

Chages:
    * Should be *much* faster, than the previous version
