  * in their file should include this file. The following are macros that the
  * trace file may define:
  *
- * TRACE_SYSTEM defines the system the tracepoint is for
+ * TRACEPOINT_SYSTEM defines the system the tracepoint is for:
+ *     < [com_company_]project_[component_] >
  *
- * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h
- *     This macro may be defined to tell define_trace.h what file to include.
- *     Note, leave off the ".h".
+ * TRACEPOINT_INCLUDE_FILE if the file name is something other than
+ *     TRACEPOINT_SYSTEM.h. This macro may be defined to tell
+ *     define_trace.h what file to include.  Note, leave off the ".h".
  *
- * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace
- *     then this macro can define the path to use. Note, the path is relative to
- *     tracepoint_event.h, not the file including it. Full path names for out of tree
- *     modules must be used.
+ * TRACEPOINT_INCLUDE_PATH if the path is something other than within
+ *     the system's include/tracepoint/ path, then this macro can define
+ *     the path to use. This path is relative to tracepoint-event.h, or
+ *     to the include search path. Trick: Use a
+ *       #define TRACEPOINT_INCLUDE_PATH .
+ *     combined with -Ipath_to_header as compiler argument to allow
+ *     searching for a header within your project build tree.
