13741N/A<para><literal>&cmd;</literal> provides classes for client interactions. It relies on the classes in libedata-book which runs in an instance of Evolution Data Server to provide the data.
10139N/A<para><literal>libedata-book-1.2</literal> provides classes for backend implementation. Writing an address book backend for the Evolution Data Server involves extending the EBookBackend class and implementing its virtual methods. Backends that require network communication generally extend the EBookBackend class. This class makes sure the backend return the results of its operations asynchronously. Other backends, including the file and vcf ones, extend EBookBackendSync, which is derived from EBookBackend and provides wrappers around its virtual functions to facilitate backend implementation when network performance is not of concern.
