 Would you mind using the new SPDX tags documented in Thomas patch set
 [1] rather than this fine but longer legalese?

 And if you could spread the word to others in your team this would be very 
 nice.

Thank you!
I reckon it took me a minute to figure why you were making a somewhat
cryptic URL related comment.
Then I realized that I had made a rather unfortunate typo, or may be
it was a freudian slip of sorts :D

Sigh. That's a lot! Now I have the tool to spot all these differences.
I need to run this and review.
As a first pass aligning the MODULE_LICENSE with the top level would
be something that requires minimal discussion I guess.

Per module.h this means GPL2 or later. This is not matching your
license above which does not state any version and therefore would
mean GPL1 or later,
Please make sure you use something and common rather than this and
make sure your MODULE_LICENSE is consistent with the top level
license.

Was it this way in the code from Krzysztof?
