I am looking at the Zstandard library and it says that it is dual licensed, BSD and GPLv2. What does it mean? If I use libraries in a non open source program will the license be GPL or BSD?
In the source files I can see this text:
you may select either version 2 of the GNU General Public License ("GPL") or BSD license ("BSD").
Does this mean that I can use the code and just apply the BSD license to it?
