[vtk-developers] Attributing VTK in a commercial app

Hi David,

I think you're making a mountain out of a molehill.  This really isn't
even a VTK-specific issue, since I'm sure that your application uses
tons of other bsd-licensed code in addition to VTK.

The license says nothing about what you put into the "About" box.  If
you want, you could add a couple lines to say "This software makes
use of the following third-party open-source libraries:" and list the
packages that you use the most heavily.  Again, this is totally optional,
it's just a courtesy.

Assuming that your commercial app has documentation, you should
list the VTK license in an appendix.  Just say the following:
"This software makes use of VTK, copyright (c) Ken Martin, Will
Schroeder, and Bill Lorensen.  The VTK license is shown below".
In fact, I'm sure that it instead of saying "shown below", it would be
okay to simply link to the above-referenced web page (that's what
the source files themselves do).

Yes, Kitware should be updating the date in the copyright file.

 - David
