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