### Configuring Octopress:
###   Under _config/ you will find:
###       site.yml, deploy.yml
###   Here you can override Octopress's default configurations or add your own.
###   This Rakefile uses those config settings to do what it does.
###   Please do not change anything below if you want help --
###   otherwise, you're on your own ;-)
