The iconservice provides a way to define sets of icons (aka theme packs) to be used in Sakai and in Sakai related tools, these theme packs allow us to have a consistent url for appliction developers to use for useful icons to increase the usability and user friendliness of their applictions, while allowing the actual icons used to be changed. At first changing icon theme packs will be done through sakai.properties, in later iterations this will change to choose the theme at run time based on some user or system variables.
