https://libwebsockets.org/pipermail/libwebsockets/2019-April/007937.html thanks to Bruce Perens for noting it. This doesn't change the intention or status of the CC0 files, they were pure CC0 before (ie, public domain) and they are pure CC0 now. It just gets rid of the (C) part at the top of the dedication which may be read to be a bit contradictory since the purpose is to make it public domain.

|
|
* other threads cleanly. Two other threads are started, which fill
|
|
* a ringbuffer with strings at 10Hz.
|
|
*
|
|
* The actual work and thread spawning etc are done in the protocol
|
|
* implementation in protocol_lws_minimal.c.
|
|
*
|
|
* To keep it simple, it serves stuff in the subdirectory "./mount-origin" of
|
|
* the directory it was started in.
|
|
* You can change that by changing mount.origin.
