README, environments, rackup about combustion HOT 2 CLOSED

Great pickup, and that is certainly a reasonable point of confusion.

What I've just done now is remove the :group => :test option from the README, as I feel the config.ru file is correct. The labels are confusing, though… in a Rails app, yes, your choices are usually between development, test, and production. In a gem, though, you're really considering runtime dependencies vs development dependencies (as defined in your gemspec file). The config.ru is referring to development in the latter context.

From the perspective of a Gemfile, though - all gems there can be considered development dependencies, as they're not in the gemspec, and thus cannot be considered runtime dependencies. So, no group label is required at all.

From the perspective of engine/gem coding, I think the right approach is to use the :default and :development Bundler groups - though I welcome feedback on situations where this shouldn't be the case!
