This script updates the list of years in the copyright notices in
|
|
most files maintained by the GDB project.
|
|
|
|
Usage: cd src/gdb && python copyright.py
|
|
|
|
Always review the output of this script before committing it!
|
|
A useful command to review the output is:
|
|
% filterdiff -x \*.c -x \*.cc -x \*.h -x \*.exp updates.diff
|
|
This removes the bulk of the changes which are most likely to be correct.
