Minecraft Server Properties Configurator

Minecraft Server Properties Configurator is a lightweight application written in Java that will help you configure your own Minecraft Survival server. With the help of  Minecraft Server Properties Configurator you can save these configurations for later use, restore them, or revert to default settings.

The program also includes the facility for making a gzipped backup archive containing all of the files describing a Minecraft beta multiplayer server as well as a packed server.properties file for easy resumption of play.

The tool can also read the seed value of any Beta level, Single Player or Multiplayer, such that you can generate a blank, untouched world identical to the one you've started with without having to resort to a standalone seed reader.
