Addresses for GNUstep is a versatile address book application for managing contact information. It stores addresses, phone numbers, pictures, instant messaging information, email, homepages and whatever. Addresses is also a framework that allows access to the addresses database in a way that is sourcecode-compatible with Apple's AddressBook.framework. It also contains a view framework to facilitate the construction of applications that use the contact database. Addresses is currently being used by Ludovic Marcotte's GNUMail application. It uses and requires GNUstep.
