+Weston:  reference implementation of a Wayland compositor.
+==========================================================
+
+This README is current as of Weston 7.0.0.
+
+Introduction
+------------
+
+Weston is the reference implementation of a Wayland compositor, as well
+as a useful environment in and of itself.
+
+Out of the box, Weston provides a very basic desktop, or a full-featured
+environment for non-desktop uses such as automotive, embedded,
+in-flight, industrial, kiosks, set-top boxes and TVs. It also provides a
+library allowing other projects to build their own full-featured
+environments on top of Weston's core.
+
+A small suite of example or demo clients are also provided: though they
+can be useful in themselves, their main purpose is to be an example or
+test case for others building compositors or clients.
+
+
+Slackware-specific Information
+------------------------------
+
+*****************************************
+IMPORTANT:  MANUAL INTERVENTION REQUIRED.
+*****************************************
+
+This SlackBuild of Weston takes a fairly "hands off" approach, and there
+are a few things users need to be aware of.
+
+Firstly, it is, by default, patched to remove the PAM dependency. This
+necessitates the elimination of the "-u" option of `weston-launch`, as
+PAM is required for that feature to function.
+
+To launch Weston, here are some required steps.
+
+1. You must add a group to your system called "weston-launch". You may
+do so, for instance, by running the following as root:
+
+	# groupadd weston-launch
+
+2. Add users to the "weston-launch" group that you would like to be able
+to run weston-launch:
+
+	# usermod -a -G weston-launch $USER
+
+3. The `weston-launch` must be setuid root. This comes with the standard
+warnings associated with doing so.
+
+	# chmod +s /usr/bin/weston-launch
+
+4. If you do not have another script exporting XDG_RUNTIME_DIR, you
+should enable the one that comes with this SlackBuild:
+
+	# chmod +x /etc/profile.d/weston.sh
+		(or .csh, depending on your shell)
+
+Once you've logged out and back in as a normal user that has been added to the
+"weston-launch" group from a virtual console,  you should be able to run
+`weston-launch` from that virtual console, and Weston will then launch and run
+directly in that console.
+
+You can use the Ctrl+Alt+Backspace keyboard combination to kill Weston.
+
+
+PAM
+---
+
+Ordinarily, PAM is a mandatory dependency for Weston. This SlackBuild of
+Weston is, by default, patched to remove that dependency. If you happen to
+have PAM installed on your system and would like to build Weston with PAM
+support, make sure the USE_PAM variable is set to "true" (nb: nothing else,
+such as "1", "yes", "on", etc. will work) before running the SlackBuild. 
+For example:
+
+	# USE_PAM=true ./weston.SlackBuild
+
+
+Optional Dependencies
+---------------------
+
+Above and beyond the hard dependencies listed in the .info file, Weston
+contains many optional dependencies. Kindly consult the documentation
+for a complete list.
+
+At the present time, the only optional dependency that this SlackBuild
+accounts for is colord, which is disabled by default. That is because
+colord pulls in many large dependencies, most of which are present on
+-current (at the time of writing) but not on 14.2, so disabling it seems
+like a sensible default on a balance of convenience.
+
+If you would like to enable colord functionality in this SlackBuild,
+set the USE_COLORD variable to "true" before running the SlackBuild.
+
+
+Known Issues
+------------
+
+I have not had success getting Weston to launch with the proprietary nvidia
+drivers in use. YMMV. I have had the best luck with the Intel KMS drivers.
