Defined in:
lib/vagrant/bundler.rb

Overview

This is a custom Gem::Resolver::Set for use with vagrant "system" gems. It allows the installed set of gems to be used for providing a solution while enforcing strict constraints. This ensures that plugins cannot "upgrade" gems that are builtin to vagrant itself.
