I notice that form_for tags in rhtml files end with “>” instead of “>”. What does the ‘’ indicate?

Hmm, rather ignore the whole thing. Don’t seem to be able to include sciptlet tags in the posts.
What i’m trying to ask is why a minus(-) sign is used in the form_for tags in the rhtml files? The minus is also then used in the corresponding end tag.

I compared html source with and without the minus in the form tag, and it looks like excluding the minus forces a line break in the resulting html directly after the form tag.
So not as significant as i was expecting.
