hi there

i'm new to click and i don't fully understant the meaning of pipes ( |
) and double pipes ( || ) in click configurations.

i undertand that double pipes are used in overloading, but are there
more uses/meaning? and what about single pipes?

last question about clicky: is it only useful for reading hand written
configurations or is it able to build a configuration graphically
using elements as building blocks?

thanks
luca

Prima di tutto vennero a prendere gli zingari e fui contento, perché
rubacchiavano.
Poi vennero a prendere gli ebrei e stetti zitto, perché mi stavano antipatici.
Poi vennero a prendere gli omosessuali, e fui sollevato, perché mi
erano fastidiosi.
Poi vennero a prendere i comunisti, e io non dissi niente, perché non
ero comunista.
Un giorno vennero a prendere me, e non c’era rimasto nessuno a protestare.
