deploy a webfaction.com Node application using Git

.gitignore

# we'll ignore webfaction's node and npm
# but we'll keep bin/start and bin/stop

node_modules/
lib/npm/
bin/node
bin/npm

#ignore the process number file too
run/

Intro

* All of this is basically as described [Quick and Dirty Git Deployment](http://someguyjeremy.com/blog/quick-and-dirty-git-deployment). 
* Also see: [A Web Focused Git Workflow](http://joemaller.com/990/a-web-focused-git-workflow/).

## On the server
- Make bare repo in a private folder and move into it
- git config
	- core.bare False
	- core.worktree [app directory]
	- receive.denycurrentbranch ignore
- Add gitignore to the worktree
- Add and commit files from worktree
- write post-receive hook in repo index 

## On local machine
- git remote add source ssh://user@server.webfaction.com/~/repos/repo
- git pull source master
- make changes and commit
- git push source master

post-receive
