Description
All four links that appear here in documentation: https://ruby.github.io/rake/index.html#label-Rake+Information are broken
It appears that usage of {Rake command-line}[link:doc/command_line_usage.rdoc] works within github but fails in rdocs.
Doing the following changes works in rdocs
-* {Rake command-line}[link:doc/command_line_usage.rdoc]
+* {Rake command-line}[rdoc-ref:command_line_usage]
