+Docker is an open-source project to easily create lightweight, portable,
+self-sufficient containers from any application. The same container that
+a developer builds and tests on a laptop can run at scale, in production,
+on VMs, bare metal, OpenStack clusters, public clouds and more.
+
+To use docker as a limited user, add your user to the 'docker' group:
+
+ 	# groupadd -r -g 278 docker
+	# usermod -a -G docker <your_username>
+
+This will require logging out and back in. 
+
+To have the docker daemon start and stop with your host,
+add to /etc/rc.d/rc.local:
+
+	if [ -x /etc/rc.d/rc.docker ]; then
+		/etc/rc.d/rc.docker start
+	fi
+
+and to /etc/rc.d/rc.local_shutdown (creating it if needed):
+
+	if [ -x /etc/rc.d/rc.docker ]; then
+		/etc/rc.d/rc.docker stop
+	fi
+
+NOTE: google-go-lang is only needed at compile time - not needed for runtime.

+commit 6922f1be08111d889b0585b763b08f92d7a55e05
+Author: Tianon Gravi <admwiggin@gmail.com>
+Date:   Sat Feb 1 21:40:51 2014 -0700
+
+    Remove reference to <linux/btrfs.h>, and instead use <btrfs/ioctl.h> like we're supposed to (from btrfs-progs)
+    
+    This fixes compilation issues when btrfs.h isn't available (because we just need the relevant structs, which for userspace programs are supposed to come from btrfs-progs instead of the kernel headers).

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
