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

# directory that contains a gemspec.

# 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).
