17.11 Cleaning up empty directories

Do make your ports clean up after themselves when they are de-installed. This is usually accomplished by adding @dirrm lines for all directories that are specifically created by the port. You need to delete subdirectories before you can delete parent directories.

@dirrm lib/X11/oneko/pixmaps
@dirrm lib/X11/oneko/sounds
@dirrm lib/X11/oneko

However, sometimes @dirrm will give you errors because other ports also share the same subdirectory. You can call rmdir from @unexec to remove only empty directories without warning.

@unexec rmdir %D/share/doc/gimp 2>/dev/null || true

This will neither print any error messages nor cause pkg_delete(1) to exit abnormally even if PREFIX/share/doc/gimp is not empty due to other ports installing some files in there.
