With some great help from Nikodemus Siivola and Rahul Jain, I was finally able to get my resolver library packaged up as a simple 0.1 release. Resolver has dependencies on UFFI. It's automagically installable using asdf-install using the following incantations.

* (require 'asdf)
* (require 'asdf-install)
* (asdf-install:install 'resolver)

Check out CLiki's asdf-install page for more information.

You should then be able to use it in SBCL as follows.

* (require 'asdf)
* (require 'resolver)
* (use-package 'resolver)
* (lookup "www.findinglisp.com" 'mx) ;; etc...

If you use Resolver in any interesting projects, I'd love to hear about them.
