Hm, this gives me an idea: Given an .irbrc that looks like this:

require 'utility_belt'
UtilityBelt.equip(:all, :except =>  
[:amazon_upload_shortcut, :hash_math])

We could use irb's IRB.conf[:IRB_RC] facility to then check wether a  
configuration has been set, and act accordingly.

I'll try implementing that and report back.

Good idea. I'll try that.
