Hey All,

I've got to suck some address info out of a db, where it is stored in
all caps, like so:

   14 WEST 21ST ST
   742 NW EVERGREEN TERRACE
   PO BOX 13

And I want to pretty up the casing:

   14 West 21st St
   742 NW Evergreen Terrace
   PO Box 13

So it's mostly just title-casing, and then dealing w/certain special
components like 'NE', 'SW', 'PO' and so forth.

I've actually got some vb.net code that I could convert, but I thought
I'd ask here whether someone's already got something they've sweated
over before I did.

Also--more concretely: for simple title-casing, is this the
easiest/best approach?

pretty_address = my_address_var.split.each do |c| c.capitalize
end.join(" ")

Or is there something more graceful/efficient?

Thanks!
