How to use it?

WARNING! Distributions with / in their names aren't supported by Quicklisp, because my commit was reverted. File the issue at the quicklisp-client's repo or switch to the CLPM which works with custom Ultralisp distributions.

Open your Lisp REPL and eval:

(ql-dist:install-dist "http://dist.ultralisp.org/digikar99/specialized-array-dispatch.txt"
                      :prompt nil)

Or if you are using Qlot, put this line into the beginning of your qlfile:

dist ultralisp http://dist.ultralisp.org/digikar99/specialized-array-dispatch.txt

Or if you are using CLPM, put these lines into your clpmfile:

(:source "digikar99/specialized-array-dispatch"
 :url "https://clpi.ultralisp.org/digikar99/specialized-array-dispatch/"
 :type :clpi)
