Both ports have been unmaintained for over six years. One succeeded the other until x11/dwm came around and took over.
We'll never see updates to these again, upstream homepages and/or documentation at suckless, googlecode and whereever else have been purged. Anselm R. Garbe keeps distribution tarballs at dl.suckless.org these projects originated from there, but he'd be happy to see the ports removed. New users are encouraged to use dwm. Thoughts? OK to remove x11/wmi and x11/wmii?
