Question regarding unix sockets

[pgundlach]

I am not sure if this is the right place. In src/unix.h I see the note

This module is just an example of how to extend LuaSocket with a new domain.

What does that mean?

• Is the code in unix.c/h not recommended to be used? (Any drawbacks?)
• Is there another way to create unix sockets without socket.unix (with the luasocket library and using only pure Lua)?
