1. Can you explain 'factory class' to me?

2. I need some self defined functions in various packages. Currently I
declare them in my base class 'NAC::DBI' and use the oo inheritance to =
call
them with '__PACKAGE__->functionname(variable1, variable2)' although I =
don't
use $self inside the function -> BAD THING.
Should I create an independent library for them and 'use' them in all
packages where I need them?
