# The Specification class contains the information for a gem. Typically
# defined in a .gemspec file or a Rakefile, and looks like this:

# s.name = 'example'

# s.licenses = ['MIT']
# s.summary = "This is an example!"
# s.description = "Much longer explanation of the example!"
# s.authors = ["Ruby Coder"]

# s.files = ["lib/example.rb"]
# s.homepage = 'https://rubygems.org/gems/example'
# s.metadata = { "source_code_uri" => "https://github.com/example/example" }

# metadata. See #metadata for restrictions on the format and size of metadata

# the platform to the appropriate value for the system on which the build is
# being performed.

# If this attribute is set to a non-default value, it will be included in
