Installing it !
From scratch (git repo)
This is the recommended installation process. Wmfs is still younger, so the code change every day and any package/build is often obsolete.
To install WMFS, you need to satisfy some dependencies: CMake>=2.6, Freetype, Xlib, Xft. (And, optionally, Doxygen, Xrandr, Xinerama ...), you also need git to clone the source code.
git clone git://git.wmfs.info/wmfs.git mkdir wmfs/__build__ cd wmfs/__build__ cmake .. make sudo make install
Then start wmfs as you can or via ~/.xinitrc and startx
echo "exec wmfs" >> ~/.xinitrc startx
On FreeBSD
There is a port on x11-wm/wmfs that you can install with
make -C /usr/ports/x11-wm/wmfs install
Warning : This port is an old version of wmfs... Bug reports for this version will be ignored. You're encouraged to use the git version.
