^head1 SEE ALSO

This class allows \"overlay\" methods to be placed
into the following files _Overlay is for a System overlay by the original author,
_Vendor is for 3rd-party vendor add-ons, while _Local is for site-local customizations.  

These overlay files can contain new subs or subs to replace existing subs in this module.

If you'll be working with perl 5.6.0 or greater, each of these files should begin with the line 

   no warnings qw(redefine);

so that perl does not kick and scream when you redefine a subroutine or variable in your overlay.

${class}_Overlay, ${class}_Vendor, ${class}_Local
