--Getting derby

This build was compiled with Derby 10.9.1.0. You should
be able to download it here:
http://db.apache.org/derby/releases/release-10.9.1.0.cgi

You'll find derby.jar in the release's lib folder.


--Installation

Put the plugin jar in your plugin directory, and if you 
don't already have one, add a folder named lib. Then 
put derby.jar in the lib folder.

--Commands

This plugin adds the player commands:
 /getblocklog - Gets the log of changes for the last location a block was placed
	permission: BlockLoggingPlugin.getblocklog
 /rollbackregion - rolls back the changes of a user over an area defined by two block placements
	permission: BlockLoggingPlugin.rollbackregion
 /redoregionblockchanges - redoes the changes of a user over an area defined by two block placements
	permission: BlockLoggingPlugin.redoregionblockchanges

--Configuration
When started a configuration file is generated under plugins/NtfLogPlugin/config.yml

history_size - your preference for how many changes should be saved for each block (Note: There is a 5 change margin given before a deletion round)

--A Suggestion

When you decide to delete your old worlds and generate new ones, you should delete the old database folder as
well. This way you won't erroneously get logged block changes from a previous world.
