 +=====grabit=====
 +Some projects encountered this semester, or in other classes that utilize lab46, will provide you resources that you can access via the '**grabit**' tool. This is one such project, where your successful utilization of the **grabit** tool, before a certain point in the project lifecycle, will be evaluated.
 +
 +Using your investigative skills cultivated in this class, figure out how to use the **grabit** tool to obtain the project files provided for this project.
 +
 +Do note: as an attempt to ensure some element of time management is practiced, you will want to perform this step by the Sunday prior to the due date of the project.
