functionals_critical(test_changed_files, t) click to toggle source

Rake is so weird, but to define a task all code inside the task is evaluated at definition time This has lead to splitting out the methods, so that when defined they should really do nothing, but when invoked they should run and output info.

I am sure this means there is a better way to do this, but I don't know it
