# Environment, set GEM_HOME & GEM_PATH. For example, we can launch JRuby like this:
# GEM_HOME=/Users/amurray/tmp/gems/ GEM_PATH=/Users/amurray/tmp/gems java -jar ~/Downloads/jruby-complete-1.7.0.preview1.jar -S irb

# =====================
# LISTING gems   
puts Gem::Specification.find_all.to_s
puts Gem::Specification.find_all.map{|spec| "#{spec.name} (#{spec.version})" }

Stuff that only goes in one locale (such as an admin section) or that can't be translated yet (if you use external translators) can simply go in files that don't match the path "config/locales/??.yml", like "config/locales/wip.fo.yml".
