module Bundler

Some versions of the Bundler 1.1 RC series introduced corrupted lockfiles. There were two major problems:

As a result, Bundler 1.1 contains code that fixes the earlier corruption. We will remove this fix-up code in Bundler 1.2.

Ruby 1.9.3 and old RubyGems don't play nice with frozen version strings rubocop:disable MutableConstant

Constants

Deprecate
FREEBSD
NULL
ORIGINAL_ENV
SUDO_MUTEX
VERSION

We're doing this because we might write tests that deal with other versions of bundler and we are unsure how to handle this better.
