Opal HowTo Install

+== Process
+
+We followed the `Installation of Opal Zip distribution` instructions that installed Opal from a zip file.
+
+1. Download Opal distribution into the `/local/` directory
+1. Unzip the Opal distribution. Note that the zip file contains a root directory named `opal-server-{version}`.
+1. Create an Opal home directory (to facilitate subsequent upgrades) using the command `mkdir opal-home`.
+1. Create a symbolic link to the Opal server directory, using the command `ln -s opal-server-{version} opal_server`
+1. Copy the `conf` directory from the server directory into the home directory, using the command `cp -r opal-server/conf opal-home`.
+1. Create a script called `start_opal.sh` in the `/local/` directory containing the following:
+
+{{{
+#!/usr/bin/env bash
+
+echo "Starting Opal"
+
+export JAVA_OPTS="-Xmx2G -XX:-UseCompressedClassPointers"
+export OPAL_HOME="/local/opal-home"
+
+/local/opal-server/bin/opal
+
+echo "Ended"
+}}}
+
+The java options are:
+ -Xmx2G:: increase the memory allocated to Java to 2GB
+ -XX:-UseCompressedClassPointers:: Do not compress class pointers (because Opal creates too many classes?)
