# TODO: Make this store to RAILS_ROOT/permanent

# On bushido, the app directory is destroyed on every update, so everything is lost.
# The only place this doesn't happen is the RAILS_ROOT/permanent folder.
# Also, RAILS_ROOT/permanent/store is symlinked to RAILS_ROOT/public/store on every update,
# so store your publicly-accessible files here (e.g. templates, etc.)
