This script now takes command line options:
```
./update-my-copyright.pl [options]
--help | -h This help message
--quiet | -q Only output critical messages to stdout
--check-only exit(111) if there are files with copyrights to edit
--search-name=NAME Set search name to NAME
--formal-same=NAME Set formal name to NAME
```
The `--check-only` and `--quiet` options are suitable for use in a git
pre-commit script to check for out of date copyright headers.
