  13 #       Also clean directories and their contents.
  14 #
  15 # -D:: Clean directories more thoroughly
  16 #       Same as -d but try harder (change permissions first).
  17 #
  18 # -n:: Don't actually remove files, just pretend to
  19 #       Do not actually remove the files, just pretend to do so.
  20 #

  22 #       Quiet - don't report what's being cleaned.
  23 #
  24 # -x:: Clean files ignored by cg-status
  25 #       Also clean files ignored by `cg-status`, such as object files.
