spring-framework/update_copyright_headers.sh

#!/bin/sh
#
# This shell script updates the copyright headers in source code files
# in the current branch so that the headers conform to the pattern:
# <start-year>-present.
# 
# For example, "Copyright 2002-2025" will be replaced with
# "Copyright 2002-current".
#
# This has only been tested on mac OS.
