<step title="Choosing a suffix at random" src="doc/codewalk/markov.go:/next := choices/,/Shift/">
To choose a suffix we use the
- <code><a href="/pkg/rand/#Intn">rand.Intn</a></code> function.
+ <code><a href="/pkg/math/rand/#Intn">rand.Intn</a></code> function.
It returns a random integer up to (but not including) the provided
value. Passing in <code>len(choices)</code> gives us a random index
into the full length of the list.

Here's a transcript of generating some text using the Go distribution's
README file as source material:
<pre>
-$ ./markov -words=10 < $GOROOT/go/README
+$ ./markov -words=10 < $GOROOT/README
This is the source code repository for the Go source
-$ ./markov -prefix=1 -words=10 < $GOROOT/go/README
+$ ./markov -prefix=1 -words=10 < $GOROOT/README
This is the go directory (the one containing this README).
