| 27 | The bourn shell script ``gdb-events.sh'' creates the files |
| 28 | ``new-gdb-events.c'' and ``new-gdb-events.h and then compares |
| 29 | them against the existing ``gdb-events.[hc]''. Any differences |
| 30 | found being reported. |

| 34 | to this file, modifying gdb-events.sh and using its output may |
| 35 | prove easier. */ |
