  25
  26    The bourn shell script ``gdb-events.sh'' creates the files
  27    ``new-gdb-events.c'' and ``new-gdb-events.h and then compares
  28    them against the existing ``gdb-events.[hc]''.  Any differences
  29    found being reported.
  30
  31    If editing this file, please also run gdb-events.sh and merge any
  32    changes into that script. Conversely, when making sweeping changes
  33    to this file, modifying gdb-events.sh and using its output may
  34    prove easier. */
