- * 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_PROVIDER defines the provider the tracepoint is for:
- *     < [com_company_]project_[component_] >
- *
- * TRACEPOINT_INCLUDE_FILE if the file name is something other than
- *     TRACEPOINT_PROVIDER.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.
