Help on reading from config

Hey all,

I would like to write to my config, something like this:

Example:
MobSpawner: MOB_SPAWNER
Price: 12.0
Plank: PLANK
Price: 6.0

OR:

Example:
MOB_SPAWNER
Price: 12.0

I have tried a few different ways of coding it but all have failed.
I would also like this so that when a user types "/example" they get a list of the items for example:
/example output: MobSpawner, Plank etc... OR Output: MOB_SPAWNER, PLANK etc...

Any help would be greatly appreciated,

Thanks!

Take a look here:
http://wiki.bukkit.org/Introduction_to_the_New_Configuration

you can better do it like this:

Code:YAML

MOB_SPAWNER:
    Price: 12.0

Thanks for the replies!

So instead of having

Example:

MOB_SPAWNER

Price: 12.0

I should have

MOB_SPAWNER

Price: 12.0

Also how would I list these item names on command for example /items

Thanks again
