CPSInstaller provides CMF products authors with an extensible framework to help them writing installers: scripts that set up products for use in the CMF, including boring tasks such as registering or configuring skins, portal types, actions, catalog indexes, permissions, schemas, widgets, layouts, vocabularies, translations, events...
It is totally independent of CPS and is helpful when writing installers for any CMF product. However, development stopped on this product in early 2006, when CPS started using GenericSetup as the basis for installation. If you start writing installers now, we suggest you look at GenericSetup instead.
