 Scans the commit logs for commits that are potentially, illegitimately
 touching modules that are primarily maintained outside of the perl core.
 Also checks for commits that span multiple distributions in cpan/ or dist/.
-Ignores MANIFEST and Porting/Maintainers.pl.
+Makes sure that updated CPAN distributions also update Porting/Maintainers.pl,
+but otherwise ignores changes to that file (and MANIFEST).
 
 Skip the <start-commit> to go back indefinitely. <end-commit> defaults to
 HEAD.
