+Configuration flags
+===
+
+When using autotools, run "./configure --help" to see the possible
+configuration options and environment variables.
+
+When using the cmake build system the dbus-specific configuration flags that can be given
+to the cmake program are these (use -D<key>=<value> on command line)
+
+ CMAKE_BUILD_TYPE set dbus build mode - one of Debug|Release|RelWithDebInfo|MinSizeRel
+ DBUS_BUILD_TESTS enable unit test code default=ON
+ DBUS_BUILD_X11 Build with X11 autolaunch support default=ON
+ HAVE_CONSOLE_OWNER_FILE enable console owner file (solaris only) ) default=ON
+ DBUS_DISABLE_ASSERTS Disable assertion checking default=OFF
+ DBUS_DISABLE_CHECKS Disable public API sanity checking default=OFF
+ DBUS_ENABLE_ABSTRACT_SOCKETS enable support for abstract sockets (linux only) default=ON
+ DBUS_ENABLE_ANSI enable -ansi -pedantic gcc flags default=OFF
+ DBUS_ENABLE_DNOTIFY build with dnotify support (linux only) default=ON
+ DBUS_ENABLE_VERBOSE_MODE support verbose debug mode default=ON
+ DBUS_ENABLE_DOXYGEN_DOCS build DOXYGEN documentation (requires Doxygen) default=ON
+ DBUS_GCOV_ENABLED compile with coverage profiling instrumentation (gcc only) default=OFF
+ DBUS_INSTALL_SYSTEM_LIBS install required system libraries default (windows only) =OFF
+ DBUS_USE_EXPAT Use expat (== ON) or libxml2 (==OFF) default=ON [1]
+ DBUS_USE_NONCE_TCP_DEFAULT_ADDRESS Use nonce tcp default address default=OFF
+ DBUS_USE_OUTPUT_DEBUG_STRING enable win32 debug port for message output default=OFF
+
+ [1] requires installed development package of the related dependency

+API/ABI Policy
+===
+
+Now that D-Bus has reached version 1.0, the objective is that all
+applications dynamically linked to libdbus will continue working
+indefinitely with the most recent system and session bus daemons.
