[rspec-users] Cucumber - but really ruby

[James Byrne]

In the cucumber rake task I see this construct:

    t.rcov_opts = %w{--rails --exclude
lib\/ruby,lib64\/ruby,\/usr,osx\/objc,gems\/,test\/,spec\/,features\/}
    t.rcov_opts << %[--output "coverage"]

My questions is:  What do %w and % represent with respect to the
"block"? in the first case and the "array"? in the second?  I cannot
find an explanation of either usage in the documentation.
