13.3 Performing yearly copyright update (“grand-replace”)

At the start of each year, copyright notices for all source files should be refreshed by running the following command from the top of the source tree:

make grand-replace

Internally, this invokes the script ‘scripts/build/grand-replace.py’, which performs a regular expression substitution for old-year -> new-year wherever it finds a valid copyright notice.

Note that snapshots of third party files such as ‘texinfo.tex’ should not be included in the automatic update; ‘grand-replace.py’ ignores these files if they are listed in the variable copied_files.
