SDK Code License

Sorry if this has been answered elsewhere, but I was wondering what license the code in the SDK/Tools falls under. For example in the file PVRTVector.h, there is copyright information:
" @Copyright    Copyright © 2007 - 2008 by Imagination Technologies Limited."

What else to I need to be aware of when using these files? I noticed the Oolong engine has just replaced the header on these files with the Oolong license (which appears to be MIT style).



The only license the code we supply with our SDK is the copyright. We allow free usage and distribution of these files (for comercial purposes or not) but the keeping the copyright. Oolong should not have removed the copyright. I will follow up with them.


Best regards.
