[Ctk-developers] CTK license and copyright

[Julien Finet]

Hi Stephen,

Some files in CTK have been a direct work over ParaView or Slicer files.
I don't think their copyright policy allow us to take their rights, so we
can't just remove their copyrights, can we ?
It is allowed to have 2 copyrights for 1 file, isn't it?

Shall we have a "Copyrights" directory where we have all the license files ?
Please educate me on the best practice here.

Thanks,
Julien.
