ICS is an inter-process configuration sharing system. It allows one process to act as the master and manage the configuration backing storage, while other processes transparently connect to the master using an ICS::Controller::Slave class, which has the same API as the ICS::Controller::Master class and allows them to use the configuration and subscribe to changes as if the process were hosting the master controller. It is useful for projects that use multiple processes but don't want to use a desktop-wide configuration system like GConf. A demonstration is included.
