[EP-tech] Altering DajaObj/Eprint.pm behaviour without altering core code

I'm trying to do something the 'right way'*. This advice: http://wiki.eprints.org/w/Read_Only_Directories says I shouldn't be editing anything under eprints3/perl_lib/ (with a couple of exceptions). I need to alter the 'render_fileinfo' subroutine in ~/perl_lib/EPrints/DataObj/EPrint.pm. How do I achieve this without: - altering the Eprint.pm file - ending up with some 'Subroutine render_fileinfo redefined' messages - using "no warnings 'redefine';" ;o) I've tried various attempts - without success. I'm sure it can be done, and I'm sure it's a bit of perl magic I'm missing, and hopefully someone here can help! Cheers, John *http://blogs.ecs.soton.ac.uk/oneshare/2009/09/25/taking-stock-and-mopping-up-the-mess-i-made-of-eprints/
