Currently lifetimes has little docs on manual, I found **14 matches for "lifetime"** on http://static.rust-lang.org/master/doc/rust.html The [borrowed pointers tutorial mentions named lifetimes](http://static.rust-lang.org/doc/master/tutorial-borrowed-ptr.html#named-lifetimes) but doesn't mention the apostrophe symbol, newcomers might get confused about that. Same goes for manual, there's no mention to apostrophe, just some examples using **'static**. It also lacks grammar production.
