Intentions for attic directory

What are the plans for files in the attic directory? Well they be kept for reference until completely out-of-date? While not a huge file, removal would save a bit of space.

Review the contents and history of the attic directory first to understand what the files represent and whether they are still referenced. The issue is complete when the project’s retention decision is made and the attic is either kept with a clear rationale or removed safely.
