  60 Get new files from the last month (can be overridden) that haven't got
  61 enough copies in git-annex yet, then optionally execute a fast fsck to
  62 check that the files have enough copies.
  63
  64 Arguments and options after " -- " are delivered to git-allfiles(1)
  65 which delivers them further to "git log".
  66
  67 Usage: $progname [options] [ -- options_to_git-allfiles ]
  68
  69 Options:
  70
  71   --from REMOTE
  72     Get new files from Git remote REMOTE.
  73   --fsck
  74     Execute "ga fsck" after the files are copied.
  75   -h, --help
  76     Show this help.
  77   -q, --quiet
  78     Be more quiet. Can be repeated to increase silence.
  79   -r, --resume
  80     Don't execute an initial "ga sync", resume an earlier interrupted
  81     session.
  82   -v, --verbose
  83     Increase level of verbosity. Can be repeated.
