NuttX Copyright Info.

[Gregory Nutt <sp...@gmail.com>]

This was posted on the Apache legal mail system.  I thought it might be 
of general interest to other people as well, so I will repost here:

Here is better, more complete data about the Copyrights in NuttX.  The 
apps/ directory does contain a considerable amount of ported 3rd party 
code which which throws thing off a bit.  The core OS is exceptionally 
clean with mostly original code; the applications are a hodge-podge of 
original and ported code.

Identification of Copyright notices was accomplished using 'grep'.  It 
is prone to some errors in that it does not understand the context of 
the Copyright.  Some of these may not be Copyrights on the file itself 
be some reference to other Copyrighted material.  'grep' isn't smart 
enough to know the difference.:

This should be a complete accounting of all Copyrights other than any 
possible (probable) human errors.  The executive summary is that I hold 
88% of copyrights.  171 other people/organizations hold also have 
Copyrights.

Build-related files, scripts, and source files do.

[5] Major contributors from Sony have signed ICLAs (representing only 
themselves)
[6] Pinecone and FishSemi are subsidiaries of Xiaomi, major contributors 
have signed ICLAs (representing only themselves)
[7] Anthony Merlino has signed an ICLA and is the co-founder  and CTO

[8] I am not certain if Ken, David or Brennan have submitted ICLAs yet. 
   They are expected.  Ken has also verbally agreed to release his  
copyrights in the past if necessary.
[9] NX Engineering, S.A, is a defunct business wholly owned by Gregory 
Nutt.  I need to change the Copyright holder name
     to Gregory Nutt.

Hi,

We would need to refine that list to explode 3rd party code, what matters is which files we going to change the headers on to Apache.

Thanks,
Justin
