Overview

:startdoc::task run rake tasks

Simply enques the specified rake task(s) for execution. Useful when a rake task needs to be executed within a workflow. For example these are equivalent:

% rap rake test
% rake test

The only exeception is in the use of the –help option. Use –rake-help to access the rake help, and –help to access this help.
