Is this long columns of ints expected behaviour on the example?

[step21]

I am just playing around with haskell and alex. When running the example from the docs, the resulting .hs file has superfluous whitespace like a snowy mountain and long columns of integers, why? Is it some kind of test? In the closest comment it says 'GScan wrapper', whatever that means.
Maybe I just do not know enough haskell, but any insight would be great. Google and docs didn't help so far.

I suppose no one cared to make the output look nice, since it is only for consumption by the Haskell compiler.

long columns of integers

If I am not mistaken, these integers represent the transition table of the generated automaton.

Thanks for clarifying, that makes sense. However I thought that as it is supposed to be usable for lexer/parser generation, I actually need to know what it is doing.
