+rempty
+------
+
+This utility removes all empty directories under the tree(s) specified on
+the command line. It's useful for cleaning up after inconsiderate programs
+that create empty directories as a matter of course. For example:
+
+ rempty "${XDG_CONFIG_HOME:-~/.config}" "${XDG_DATA_HOME:-~/.local}" "${XDG_CACHE_HOME:-~/.cache}"
+
+This can clean up after many messy programs that otherwise conform to the XDG
+base directory specification.
