Mostly this script cleans up Hot Reload DLLs that often get left over. It used
to also call git lfs prune but has stopped doing that for now because
of a previous bug in Git LFS which would delete stashed LFS files.
I don't use this script very much any more because I'm using Live Coding now. The script also cleans up Live Coding patches but there's fewer of those.
