-# STEPS FOR BIG CLEANUP
-#
-# 1. Change TODO to your name (in capitals) for each file in the list below
-#    that is yours (or you are going to fix)
-# 2. Update the name between parentheses below this list (see comment) to your
-#    name
-# 3. Create a git commit at this point (ensure `git status` reports "working
-#    tree clean")
-# 4. Run `make format` in the REPOSITORY ROOT DIRECTORY (NOT HERE), and start
-#    fixing reported errors or miscorrections manually until everything works
-#    again.
-# 5. Once everything is working again, create another git commit, and create a
-#    pull request. Make sure to ask someone to review the code standards for
-#    each ENTIRE FILE in this pull request.
