Hi Inkscape Developers and Designers,

I'm involved with the application VisiCut, an opensource and more userfriendly application to talk to Lasercutters.
http://visicut.org/

One of the things I'd like to do is introduce better icons. I really like you guys work on the Tango icons for Inkscape.

So I'd like to properly credit the authors / designers. Could you guys help me out on how to do that?

At the moment I would use:

Tango Icon Library 0.8.90 (tango)
    link: http://tango.freedesktop.org/Tango_Icon_Library
    license: Public Domain 

Inkscape (inkscape)
    link: http://www.inkscape.org/
    license: GPLv2

I found the icons in the Open Icon Library, but it's a bit unclear which icon is from which source. 

Great work on Inkscape btw, I'm involved with Fablab Amersfoort and it's one of the tools we advocate. 

Thanks in advance,
Best regards,
Peter Uithoven
