This plugin will allow the players on the server to create factions/guilds. The factions can claim territory that will be protected from non-members. Factions can forge alliances and declare themselves enemies with others. Land may be taken from other factions through war.

With this plugin...

The players will effectively take care of anti-griefing themselves.
There will be politics and intrigues on your server.
The players can enjoy guilding and team spirit.

Installing

Download the latest release: latest.zip
Put the included gson.jar here /your_server_folder/gson.jar
Put the included Factions.jar here /your_server_folder/plugins/Factions.jar

Compiling

You will need the Bukkit library to compile (Bukkit.jar)
You can download it here: http://bamboo.lukegb.com/browse/BUKKIT-BUKKITMAIN/

You will also need Google GSON in your build path.
You can download it here: http://code.google.com/p/google-gson/
OR you can use the file in this repo /packaging/gson.jar
However you won't get javadocs and source that way.

You will need to include the MANIFEST.MF and plugin.yml in your jar. All bukkit plugins need a plugin.yml and the MANIFEST.MF is needed for the plugin to find the gson.jar (wich should be in the same folder as the main server jar when running the server).
