------------------------------------------------------
[PREREQ] Recovery
------------------------------------------------------
Recommend installing 'applejack' (http://applejack.sourceforge.net), to ensure you have an easy way to fix problems in single user mode, should they occur (they will most likely occur). You can enter single-user mode by holding down 'command key + s' on boot.

------------------------------------------------------
[TECH TIP] Sudo setuid bit
------------------------------------------------------
If you mess up and can't sudo to root anymore, run 'applejack' in single-user mode. WARNING: If you run 'applejack' without booting into single-user mode, you could bork the entire system!

------------------------------------------------------
[IAVA PREREQ] MacPorts and XCode
------------------------------------------------------
For IAVA compliance, you will need to install MacPorts to upgrade (at a minimum) OpenSSL (openssl version; port install openssl) and PHP (php -v; port install php5). To install MacPorts, you will need XCode first, which is available on the OS X Install DVD (OEM). You can also download the .dmg (disk image) from Apple.

------------------------------------------------------
[IAVA PREREQ] Retina
------------------------------------------------------
To scan with Retina, you will need to enable the SSH daemon (SSHD) in "System Preferences" --> Sharing (disable when complete); you must add an entry for the Retina server in /etc/hosts; and ensure you turn off the firewall before scanning and re-enable when complete.

------------------------------------------------------
[TECH TIP] Software utilities you might need
------------------------------------------------------
1. BatChmod;
2. MacPorts;
3. AppleJack (mentioned above);
4. Disk Inventory X.

Google them.

------------------------------------------------------
[TECH TIP] IAVA Updates
------------------------------------------------------
1. Update all system software;

[TECH TIP] Logging
------------------------------------------------------
Your logs will not be overwritten, even if you have to ctrl+c/break out of the script. Each will be date/time stamped for your review and will be available in the logs/ directory. However be advised they may become very large if the script hangs and you must forcefully kill terminal, and the child process continues to output error data.

------------------------------------------------------
[TECH TIP] Script Sequence
------------------------------------------------------
The script is split into three parts (part1, part2, part3). The main script.sh will take you through all three in sequence, although you may wish to run them individually.

------------------------------------------------------
[TECH TIP] Using 'locate' instead of 'find'
------------------------------------------------------
