Precious: Keep your Bundler release tagging (<3), without pushing to RubyGems.org
This is a very simple gem that pulls in the Rake helpers from Bundler, but neuters the pushing to RubyGems. Having Bundler tag-and-push your gems to Git is wonderful. Having it push your internal-only gems to RubyGems, well, isn't.
In your gem's Rakefile
require 'repcious' # Replace 'Bundler::GemHelper.install_tasks' with: Precious::GemHelper.install_tasks # Recommended, but not required: task :release => :spec
I've currently evaluating I might better test this, so please stay tuned. Currently, a test exists only to verify that it prints a warning if Bundler's version is untested with this gem.
