NAME
copyright.t
DESCRIPTION
Tests that the latest copyright years in the top-level README file and the perl -v
output match each other.
If the test fails, update at least one of README and perl.c so that they match reality.
Optionally you can pass the --now
option to check they are at the current year. This isn't checked by default, so that it doesn't fail for people working on older releases. It should be run before making a new release.
