- * Trace files that want to automate creationg of all tracepoints defined
- * in their file should include this file. The following are macros that the
- * trace file may define:
- *
- * TRACEPOINT_SYSTEM defines the system the tracepoint is for:
- * < [com_company_]project_[component_] >
- *
- * 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".
- *
- * 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.
