Rakefile

# This file is a rake build file. The purpose of this file is to simplify
# setting up and using Awestruct. It's not required to use Awestruct, though it
# does save you time (hopefully). If you don't want to use rake, just ignore or
# delete this file.
#
# If you're just getting started, execute this command to install Awestruct and
# the libraries on which it depends:
#
#  rake setup
#
# To run in Awestruct in editor mode, execute:
#
#  rake
#
# To clean the generated site before you build, execute:
#
#  rake clean preview
#
# To get a list of all tasks, execute:
#
#  rake -T
#
# Now you're Awestruct with rake!
