+This is a port of OpenBSD's excellent cwm[0] to Linux and other
+Unices.
+
+    cwm is a window manager for X11 which contains many features that
+    concentrate on the efficiency and transparency of window
+    management.  cwm also aims to maintain the simplest and most
+    pleasant aesthetic.
+
+This port requires pkg-config, Xft, Xinerama and Xrandr.  The included
+Makefile should work with both GNU make and BSD make.
+
+This version actively tracks changes in the OpenBSD CVS repository.
+Releases are roughly coordinated.
+
+The revision controlled version is at https://github.com/chneukirchen/cwm
+Releases can be found at http://chneukirchen.org/releases
+
+ChangeLog:
+
+2012-05-02: First public release 5.1 of portable cwm.
