EXECUTABLES = ['bin/rails', 'script/rails']
+ BUNDLER_WARNING = <<EOS
+Looks like your app's ./bin/rails is a stub that was generated by Bundler.
+
+In Rails 4, your app's bin/ directory contains executables that are versioned
+like any other source code, rather than stubs that are generated on demand.
+
+Here's how to upgrade:
+
+ bundle config --delete bin # Turn off Bundler's stub generator
+ rake rails:update:bin # Use the new Rails 4 executables
+ git add bin # Add bin/ to source control
+
+You may need to remove bin/ from your .gitignore as well.
+
+When you install a gem whose executable you want to use in your app,
+generate it and add it to source control:
+
+ bundle binstubs some-gem-name
+ git add bin/new-executable
+
