      4 filesystem name and percentage are stored in a list. A simple report is
      5 printed. Filesystems over 95% capacity are highlighted. Note that this does not
      6 parse filesystem names after the first space, so names with spaces in them will
      7 be truncated. This will produce ambiguous results for automount filesystems on
      8 Apple OSX. """
