Use of [1:] in fmt.Println

[ddritzenhoff]

Hey,

I just wanted to first and foremost thank you for the amazing code that you wrote. This has been my de-facto north star when creating a Go project myself.

I do have a question though!

1: What is the point of adding [1:] here? I tried removing it in the Go playground and saw absolutely no difference. My understanding is that you create one big string, which is just a slice of bytes, and you remove the first byte from that slice for some reason.

Cheers :)

It's to remove the leading newline used to make the output line up nicely in the Go code...unlike this:

	fmt.Println(`Manage WTF dials you own or are a member of.
Usage:
	wtf dial <command> [arguments]
The commands are:
	list        list all available dials
	create      create a new dial
	delete      remove an existing dial
	members     view list of members of a dial
	set         set your WTF level for a dial
