This is a world generator that creates a world with only those blocks that you want it to have. I created this just for fun after a request for such a world within my HothGenerator plugin.
The default setting creates a crazy world with huge amounts of valuable ore and .. ore trees.
The plugin does not have any configuration. But each world that you create will have its own configuration file where you can define which features and blocks types that it should have.
The config files are called worldname.lst
Where worldname is the name of the world.

Commands to create a world
With Multiworld:
/mw create oreworld plugin:OreWorld
With Multiverse:
/mv create oreworld normal -g OreWorld
World config file description:
The config file consists of a few options and a list of blocks.
The lists of blocks are those blocks that you want rendered into the world.
In minecraft all blocks have a typeID and a Data value. The typeID represents the block type, such as sand, stone, logs and such. While the data value is a variant of the block, such as different colors for glass or different rotations of stairs.
You can find typeID and data values here: http://minecraft.gamepedia.com/Data_values#Block_IDs
Each line with a block description in the file has this format:
TypeID,DataValue,Description
The description isn't used for anything. It's just there to help the person that is editing the file since it might be difficult to remember what the numbers mean. Don't put any commas in the description since that will break the parser.
Any lines starting with a ";" and any empty lines are ignored by the plugin. That way you can add comments if you wish.
Remember that if you change the contents of the file then any chunk that have already been rendered will not be updated. If you want to remake the whole world with your new blocks then you have to stop the server, delete everything in the worlds region/ folder (like oreworld/region/*) and restart the server.
