      description "Use the **breakpoint** resource to add breakpoints to recipes. Run the #{Chef::Dist::SHELL} in #{Chef::Dist::PRODUCT} mode, and then use those breakpoints to debug recipes. Breakpoints are ignored by the #{Chef::Dist::CLIENT} during an actual #{Chef::Dist::CLIENT} run. That said, breakpoints are typically used to debug recipes only when running them in a non-production environment, after which they are removed from those recipes before the parent cookbook is uploaded to the Chef server."
