COPYRIGHT.txt

[Silviu-Caprar]

Hi,

There are some files in the hs_client folder which refer to COPYRIGHT.txt, nowhere to be found.
Some files have only the DeNA Co. copyright but others have also Kentoku Shiba copyright.

As I've done a little research, I have found the COPYRIGHT.txt for libhsclient here:
https://github.com/DeNA/HandlerSocket-Plugin-for-MySQL/blob/master/libhsclient/COPYRIGHT.txt

Does the BSD-3-Clause from COPYRIGHT.txt and also the GPL version 2, under which spider is licensed apply on the files with both the DeNa Co. and Kentoku Shiba copyrights ? Or which license applies on this specific files ?

Thanks.
