It's a shorthand used for creating arrays of strings:

   %w{a b c d}  #=> ["a", "b", "c", "d"]

Basically, the character that follows `%w' is the delimiter. So:

   %w<delimiter> foo bar baz <delimiter> => ["foo", "bar", "baz"]

i.e.

   %w& foo bar &  #=> ["foo", "bar"]

If the starting delimiter is `(', `{', `[', or `<', then the matching 
closing symbol will be the closing delimiter:

   %w<foo bar baz>  #=> ["foo", "bar", "baz"]
