license=(o) Instance Public methods The license for this gem. The license must be a short name, no more than 64 characters. This should just be the name of your license. The full text of the license should be inside of the gem when you build it. You can set multiple licenses with licenses= Usage: spec.license = 'MIT'

licenses=(licenses) Instance Public methods The license(s) for the library. Each license must be a short name, no more than 64 characters. This should just be the name of your license. The full text of the license should be inside of the gem when you build it. Usage: spec.licenses = ['MIT', 'GPL-2']

requirements() Instance Public methods Lists the external (to RubyGems) requirements that must be met for this gem to work. It's simply information for the user. Usage: spec.requirements << 'libmagick, v6.0' spec.requirements << 'A good graphics card'

test_files=(files) Instance Public methods A collection of unit test files. They will be loaded as unit tests when the user requests a gem to be unit tested. Usage: spec.test_files = Dir.glob('test/tc_*.rb') spec.test_files = ['tests/test-suite.rb']
