Subject: including newlines in a .sub

Hi, I'm new to ruby, and am having trouble with the following (\n is 
newline on a Mac).

e.g.

line = "foo bar"
line = line.sub(/ /, '\n')
puts line

This produces:

foo\nbar

when what I want (and expected) was:

foo
bar

(This is just a toy example; I don't actually want to split lines on 
spaces.) What I don't understand is how to insert a true newline into a 
string so that it outputs as such.

Thanks

Alan
