/**
 * @mainpage libdpkg C API
 *
 * This is the documentation for the libdpkg C API. It is divided in an
 * @ref dpkg-internal "internal API" and a @ref dpkg-public "public API".
 * Applications closely tied to dpkg can make use of the internal API, the
 * rest should only assume the availability of the public API.
 *
 * Applications need to define the LIBDPKG_VOLATILE_API macro to acknowledge
 * that the API is to be considered volatile, please read doc/README.api for
 * more information.
