# Manifests are not intended to be accessed publicly, but typically live
# alongside public assets for convenience. To avoid being served, the
# filename is prefixed with a "." which is usually hidden by web servers
# like Apache. To help in other environments that may not control this,
# a random hex string is appended to the filename to prevent people from
# guessing the location. If directory indexes are enabled on the server,
# all bets are off.
