Does executable gem need lib folder etc

I have an executable ruby file (single file) that I’d like to release as
a gem. I used bundler to create the structure. I moved my file to the
bin folder. Bundler created a lib/mygem.rb and lib/mygem/version.rb etc.

Do i really need to keep lib and these 2 files, or it enough for a gem
to have only a bin with the executable in bin.

Thanks. I have already gone through
http://guides.rubygems.org/make-your-own-gem/ — however that had all
the components. I was still not clear, so i asked.

Since there are no answers, I guess I’ll just delete the unused files
and see how it goes.
