Well, you have a choice:
if you declare them with "our" in the main program
then you get to them in other packages via
Main::<varname> or ::<varname>, if you declare them
with "our" in the require'd file, then you reference
them in the main program with <package>::<varname>, where
<package> is the name of the package that the require'd
file declares.
If you want to get fancy, declare them in the package
file, have the package "use Exporter" and define which
variables should always export into the client's namespace
(i.e. the namespace of the package doing the "use" or
"require") and which should never export, and which should
export only when asked by the client.
