# A VendorSet represents gems that have been unpacked into a specific

# 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).
