In the case that a configurable aspect of a task needs to change quite often, it can be inefficient to add it to the project configuration. This is where the use of command-line parameters can be useful as they provide us with a way to easily provide options to our task, without having to alter our configuration.
In this example, we'll work with the basic project structure we created in the Installing Grunt on a project recipe in Chapter 1, Getting Started with Grunt. Be sure to refer to it if you are not yet familiar with its contents.
If any of the steps in this recipe seem hard to follow, be sure to check out the Creating a basic task recipe provided earlier in this chapter.
