localization debugging in Rails
# Allow some helpful debugging of localization issues.
# You can see translations in the UI by adding the following (or like it) to your CSS.
# .translation_missing { background-color: red; color: white !important; }
# .translation_fallback { background-color: green; color: white !important; }
#
# You will also need to have the following in your development group in your Gemfile:
# gem 'term-ansicolor'
#
# To turn this off, change this to false.
