Bukkit

• Support for CraftBukkit 1.2.5-R4.0
• Supports custom data values (add a dash and the value, see below)
• Supports integer material IDs
• Unique systems for each world, when using a multi world plugin.

New material examples (in config.yml):

Blue Wool: - WOOL-1.0-11 or - 35-1.0-11 If you have a mod that adds a new material with an ID of 140: - 140-1.0

NOT BACKWARDS COMPATIBLE WITH OLDER PLANETOIDS VERSIONS!  This is a beta for a reason, it's not extensively tested.  Try it with a new world or risk messing up your old one.

The auto created world's seed will be set to 0.  You can fix this by adding planetoids.seed in your config with some random number.

Last time I checked, Bukkit still imposes a maximum height limit of 256.
