-XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/>
-go here.  If Module::CoreList is updated, generate an initial draft of the
-following sections using F<Porting/corelist-perldelta.pl>.  A paragraph summary
-for important changes should then be added by hand.  In an ideal world,
-dual-life modules would have a F<Changes> file that could be cribbed.
 
-The list of new and updated modules is modified automatically as part of
-preparing a Perl release, so the only reason to manually add entries here is if
-you're summarising the important changes in the module update. (Also, if the
-manually-added details don't match the automatically-generated ones, the
-release manager will have to investigate the situation carefully.)
