How exactly do you intend to use the globals?  I'm not sure that you
can ever expect to pass data between pages using global variables
when you might have several different apache processes, each with a
different "interpreter-space".

Re: option b, your code can go into regular ruby files and be required
into eruby pages or ruby scripts. You can split up your code however
it best makes sense to you. I'm not sure how you'd like to use these
globals, but if you have a number of related functions, you can put
then into a common module or class.
