```ruby
Gem::Specification.new do |s|
  s.name     = "conversions"
  s.version  = "1.1"
  s.date     = "2009-01-12"
  s.summary  = "A Ruby on Rails plugin that adds conversion capabilities to numeric objects"
  s.homepage = "http://github.com/Fingertips/conversions/tree/master"
  s.description = "A Ruby on Rails plugin that adds conversion capabilities to numeric objects"
  s.authors  = "Fingertips"
  s.email = "manfred@fngtps.com"
  s.files = Dir['[a-zA-Z]*'] + Dir['lib/**/*.rb'] + Dir['rails/*.rb'] + Dir['test/**/*']
  s.test_file = "test/unit_test.rb"
end
```

Use static file lists because otherwise gem doesn't build on Github.
