sxwm (small X11 tiling window manager)

sxwm is a small and configurable tiling window manager for X11, with
support for floating windows, nine workspaces, multiple monitors, gaps,
monocle mode, window pinning, and EWMH desktop hints.

The upstream default configuration is installed as /usr/share/sxwmrc.
Copy it to ~/.config/sxwmrc or $XDG_CONFIG_HOME/sxwmrc and customize it.

The included xinitrc.sxwm can be used to start sxwm from startx.  The
package does not replace the user's existing xinitrc or window manager
configuration.

The upstream patches are optional and are not applied by default.  To
apply all patches shipped in the source archive, use:

    PATCHES=yes ./sxwm.SlackBuild
