This is an addon module for EditableSign plugin.

When this addon is installed and enabled, a user can break the existing sign and "relocate" to elsewhere.  When you place this relocated sign, the content of the sign is retained.

Place ES-Relocate-x.x.x.jar file in plugins/EditableSign/addons folder.
Once you restart the server, EditableSign plugin will automatically integrate this addon into itself and auto-generates a default config file Relocate_config.yml.
