mirror_corosync/exec/evt.h
Steven Dake f6cfe4e86e This is a major rework of the service handling code. Now service handlers
can be dynamically loaded via the live component replacement service.  Sync
handlers are also dynamically contributed.

It is possible to build using either dynamic loading via LCR or static
linking of the entire executive.  This is controlled by the BUILD_DYNAMIC 
configuration option in the Makefile.
