# Renames uploaded "@Display Name" mod folders to short lowercase names,
# matched by the publishedid in each folder's meta.cpp (so odd characters
# in the folder names don't matter). Also lowercases everything inside and
# copies .bikey files into keys/.

# Usage:  sudo ./rename-mods.sh          (dry run, shows what it would do)
#         sudo ./rename-mods.sh --apply  (actually do it)
