Common lisp gray streams

Question

Is there a tutorial on how to use gray streams?

I want to create a class that reads from a file while looking for a specific set of bytes. My initial thought was to use gray streams, but could not find any starting information.

Answer 1

Perhaps the examples in the SBCL manual can help you for a start?

Answer 2

I found this useful. In SBCL, gray streams are in package :GRAY.
