How to exclude files in rcov(a-code-coverage-tool-in-ruby)

Today i was working on  one of my project for increasing test coverage , i want to exclude some files from testing because they are not needed, for example: helpers I am using rspec framework for testing,  In spec folder there is a file rcov.opts, in this file we have --exclude option. We can append our path of files to this. for example I want to exclude helpers , sweepers folders, so i just did

1
  --exclude "helpers/*,app/sweepers/*"

Then when i ran ruby rake spec:rcov then the excluded files did not appear in the statistics appeared in index.html file
