why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

	STUDENT: Sir, can I ask a question?
	TEACHER: Yes!
	STUDENT: How do you put an elephant inside a fridge?
	TEACHER: I don't know.
	STUDENT: It's easy, you just open the fridge and put it in. I have another question!
	TEACHER: Ok, ask.
	STUDENT: How to put a donkey inside the fridge?

	var express = require('express')
	, app = express()
	, server = require('http').createServer(app)
	, io = require('socket.io').listen(server)
	, fs = require('fs')
	, path = require('path')
	, gpio = require('rpi-gpio')

	server.listen(8000);

	brew update
	brew versions FORMULA
	cd `brew --prefix`
	git checkout HASH Library/Formula/FORMULA.rb # use output of "brew versions"
	brew install FORMULA
	brew switch FORMULA VERSION
	git checkout -- Library/Formula/FORMULA.rb # reset formula

	## Example: Using Subversion 1.6.17
	#

	# First install tmux
	brew install tmux

	# For mouse support (for switching panes and windows)
	# Only needed if you are using Terminal.app (iTerm has mouse support)
	Install http://www.culater.net/software/SIMBL/SIMBL.php
	Then install https://bitheap.org/mouseterm/
