( http://www.aps.anl.gov/asd/controls/epics/EpicsDocumentation/ReleaseNotes/ReleaseNotes3.13.4.html : "The purpose of this new facility is to allow things like logging Channel Access writes. Epics base itself does not provide this ability but only the hook needed by such a facility. DESY has developed a facility that logs CA puts. The trap writes feacure allows the DESY facility to be implemented without any changes to epics base. In addition it allows the user to decide what should be logged. This new facility will be described in more detail in the 3.14 version of the Application Developer's Guide."
