If you find WorldEdit useful, you can:

This version features official support for Minecraft up to version 1.2.

• Made #region mask keep the region selected when the mask was added, and added #dregion mask that always uses the player's current
  selection
• Allow inverted and under/overlay masks to affect masks, making them more flexible. This allows for things like /gmask !$biome and
  /gmask >>>#region
• Added basic entity handling with copy and paste. Paintings do not currently respawn properly, entity pastes cannot be undone yet, and
  schematics do not yet store entities
• Added getChunkCubes() to Region to get 16^3 chunks a region overlaps with
• Cleaned up ContainerBlock inventory reading from NBT.
• Added a command to list schematics and the abilitiy to autodetect schematic format when loading schematics

• Add FlatRegion interface and an associated iterator (for developers!)
• Fix a NPE with brush using a global mask and no brush mask
• Fixed //shift not updating polygonal regions properly.
• Add support for expand with reverse dir for Cylinder & Ellipsoid
• Make inset/outset use varargs contract/expand, so they can be used with cylinders and ellipses.
• Add positive() to Vector and Vector2D
• In WorldGuard, teleport/spawn location yaw/pitch should now work.
• Register command permissions, integrate with the Bukkit help API
• Allow annotation-free registering of commands with other plugins (for developers!)
