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

I really meant to suggest making the change in ~/archives/[ID]/cfg/cfg.d/core_overrides.pl
 - would a change in there result in this inheritance?

I need to make the change in one archive only!

Cheers,
John

Good! Yes I'd add a file in cfg.d/ as you suggested. However be aware 
that other repositories set up there (ie. archives/[id1], 
archives/[id2]...) will inherit the change!
