What to Exclude from Gemspec Files?

[Faraz Yashar]

I'm a bit unclear about what exactly needs to be kept out of the gemspec file directive.

The [RubyGems specification guide](http://guides.rubygems.org/specification-reference/#files) includes tests:

```

require 'rake'

spec.files = Dir['lib/   *.rb'] + Dir['bin/*']

spec.files += Dir['[A-Z]*'] + Dir['test/**/*']

spec.files.reject! { |fn| fn.include? "CVS" }

```

The default line that comes with bundler rejects tests but includes other things that aren't necessary for running a gem. Shouldn't dotfiles be ignored as well? What about the gemspec, Gemfile, Rakefile, or /bin?
