@noelrappin

page 323, paragraph 4, line 2 : $rdoc ?

> will likely use approximately never, see $rdoc --help for a full rundown.

The dollar prompt should be removed or separated by a blank, because the command is `rdoc --help` and is already in the special font for code literal.

+++++ in **Using RDoc to Create Documentation for ri** , paragraph 6, line 2 : _ **easiest** _ instead of _ **easier** _ ???

```auto
own use, it’s easiest to use the --ri option, which installs the documentation into ~/.rdoc:
       -----> ^^^^^^^

```

Can we say “it’s easiest”, not “it’s easier” ?
