On compiling the OLA library from source

Getting the OLA c++ source, compiling it, and running the OLA daemon with Max/MSP to send pixel control data over E131.

I had a lot of initial trouble getting OLA to compile and run on my system. My goal was to eventually control LEDs with DMX/E131 protocol using Max or another client application (built in Openframeworks, Cinder, or Processing).
I found that my library compile problems were coming from Macports. The Official OLA documentation recommends installing with Macports but in practice Homebrew was a better option for me. Here is some info on Homebrew. http://brew.sh/ Once you have homebrew installed, you should be able to run the command brew install ola --universal in your terminal, which will install OLA to /usr/local/Cellar and symlink to /usr/local/lib directory. Sometimes homebrew installs the package but does not link it. You may have to run

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

	set -e
	unset CDPATH
	unset IFS

	show_usage() {
	cat <<USAGE
	Usage: [PROJECTS_PATH=<PATH>] $(basename "$0") [--exclude-sessions] [--exclude-workspaces]

	This file remaps the key bindings of a single user on Mac OS X 10.5 to more
	closely match default behavior on Windows systems. This makes the Command key
	behave like Windows Control key. To use Control instead of Command, either swap
	Control and Command in Apple->System Preferences->Keyboard->Modifier Keys...
	or replace @ with ^ in this file.

	Here is a rough cheatsheet for syntax.
