* @short_description: #ESource extension to configure revision guards
*
* The #ESourceRevisionGuards extension configures whether revisions
* should be checked on modified objects. If a modified object has
* a conflicting revision with an existing object, then an
* %E_CLIENT_ERROR_OUT_OF_SYNC error should be produced for that object
* and the modification should be discarded.
*
* Access the extension as follows:
*
* |[
* #include <libedataserver/libedataserver.h>
*
* ESourceRevisionGuards *extension;
*
* extension = e_source_get_extension (source, E_SOURCE_EXTENSION_REVISION_GUARDS);
