+Etherpad lite is a really-real time collaborative editor spawned
+from the Hell fire of Etherpad.
+We're reusing the well tested Etherpad easysync library to make it
+really realtime.
+Etherpad Lite is based on node.js ergo is much lighter and more
+stable than the original Etherpad. Our hope is that this will
+encourage more users to use and install a realtime collaborative
+editor. A smaller, etherpad-lite: manageable and well documented
+codebase makes it easier for developers to improve the code and
+contribute towards the project.
+
+See README.Slackware for some Slackware notes setup (with things
+to do before and after building the package).
+
+abiword (with AbiCommand plugin) is required to import/export pads.

+This script requires an 'etherpad' user/group to exist before
+running.
+The recommended UID/GID is 264. You can create these like so:
+  groupadd -g 264 etherpad
+  useradd -u 264 -g 264 -c "Etherpad lite" -m etherpad
+
+After installation, Etherpad lite can be started with
+
+  /etc/rc.d/rc.etherpad-lite start
+
+if you want it to start at boot, add an entry like this
+in /etc/rc.d/rc.local
+
+  # Start etherpad-lite:
+  if [ -x /etc/rc.d/rc.etherpad-lite ]; then
+    /etc/rc.d/rc.etherpad-lite start
+  fi
+
+to stop it at shutdown, add a similar entry substituting
+"start" with "stop" in /etc/rc.d/rc.local_shutdown.
+
+Settings can be configured in /etc/etherpad-lite/settings.json
+
+Log files can be found in /var/log/etherpad-lite/
+
+If you want to use it with mysql, have a look at
+https://github.com/ether/etherpad-lite/wiki/How-to-use-Etherpad-Lite-with-MySQL

+# 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
