plugins'org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml

So I'm having this problem lately...
The plugin won't load cause there's an InvalidDescriptionException and I have no idea how to fix this kinda error...

Code:

this is my plugin.yml...

Code:

main: com.matthiaantje.mac.MAC
name: MAC
author: Matthiaantje
load: STARTUP
prefix: MangoAntiCheat
loadbefore: [Essentials]
commands: mac: description: MAC help command
usage: /mac
macon: description: enable
usage: /macon
macoff: description: disable MAC
usage: /macoff
macplayers: description: list
usage: /macplayers

Thanks in advance!

@Matthiaantje
The obvious problem is that the "commands: mac: description: MAC help command" line has multiple things on the same line. Put them on different lines. If the error isn't fixed, please post the plugin.yml using pastebin.com as [code][/code] tags are broken atm.

Not only is that the problem, but there is no formatting. All commands need to have two spaces, and all usages need to have four.
