The same way as regular phpass; check out the embedded phpdoc for info on the extras.
I wanted to implement proper hashing on my web app. password_hash seemed the way to go, but it's only supported by the most recent versions of PHP (at the time of writing this, PHP 5.5.0 was realeased just a few months ago...).
So I did some research and the most reasonably fast and tested library was phpass, but it lacked support for, guess what, password_hash. Since password_hash should be the default option (at last, a sane way to use crypt!) and none of the other phpass hacks I checked (Drupal, WordPress) had it I decided to add it myself.
In the process, adding also support for sha512 and sha256 on portable methods seemed easy enough, so I beefed that up too.
