What's gateway? Is that necessary?

The WIKI just told me how to configure it. But I don't what dose it use for.

Okay. It's necessary.

Gateway is the room/channel/discussion you wish to bridge, everything that is bridged together is a gateway, you need one for each.

E.g. to bridge two IRC channels together

[[gateway]]
name="test"
enable="true"

    [[gateway.inout]]
    account="irc.localergo"
    channel="#test"

    [[gateway.inout]]
    account="irc.liberachat"
    channel="#test"

[[gateway]]
name="secretchan"
enable=true

    [[gateway.inout]]
    account="irc.liberachat"
    channel="##secretchan+"

    [[gateway.inout]]
    account="irc.localergo"
    channel="#secretchan+"

I have a more complete example in my gist repo
