[Cin] Rendering multi-threads

[Andrea paz]

Excuse my ignorance. I don't understand points 3) and 5) of the
manual. In fact, I really don't understand how a render farm works.
If I decide to use 14 jobs in the renderfarm, starting from node 1025,
I have to open 14 terminals and in each of them write:
{path}./cin -d (or -D?) 1025
then 1026
...
1038

And then?

- "cin" gives me "unknown command" error, "./cin" works instead.

- RenderMux does nothing; I certainly don't know how to use it.
