Overview

A VendorSet represents gems that have been unpacked into a specific directory that contains a gemspec.

This is used for gem dependency file support.

Example:

set = Gem::Resolver::VendorSet.new

set.add_vendor_gem 'rake', 'vendor/rake'

The directory vendor/rake must contain an unpacked rake gem along with a rake.gemspec (watching the given name).
