Dropping bin/* files for development in the gem?

[Jun Aruga]

It's similar with ruby/power_assert#35 .

I find there are bundle console rdoc rubocop setup files under the bin/ in the rake gem file. Are these the files for a development, right? What do you think about not including the files in the rake gem file?

$ gem fetch rake
Fetching rake-13.0.3.gem
Downloaded rake-13.0.3

$ gem unpack rake-13.0.3.gem

$ ls rake-13.0.3/bin/
bundle*  console*  rake*  rdoc*  rubocop*  setup*

Seeing the current rake.gemspec excluding specific files by Array#reject, perhaps a way to include only necessary files might be a way not to include the bin/* files for development.
