# Middleman is a static site renderer that provides all the conveniences of
# a modern web stack, like Ruby on Rails, while remaining focused on building
# the fastest, most-professional sites possible
#
# Install Middleman:
#
# gem install middleman
#
# To accomplish its goals, Middleman supports provides access to:
#
#### Command-line tool:
# * **middleman init**: A tool for creating to new static sites.
# * **middleman server**: A tool for rapidly developing your static site.
# * **middleman build**: A tool for exporting your site into optimized HTML, CSS & JS.
#
#### Tons of templating languages including:
# * ERB (.erb)
# * Interpolated String (.str)
# * Sass (.sass)
# * Scss (.scss)
# * Haml (.haml)
# * Slim (.slim)
# * Less CSS (.less)
# * Builder (.builder)
# * Liquid (.liquid)
# * RDiscount (.markdown)
# * RedCloth (.textile)
# * RDoc (.rdoc)
# * Radius (.radius)
# * Markaby (.mab)
# * Nokogiri (.nokogiri)
# * Mustache (.mustache)
# * CoffeeScript (.coffee)
#
#### Compile-time Optimiztions
# * Javascript Minifiers: YUI, Google Closure & UglifyJS
# * Smush.it Image Compression
# * CSS Minification
#
#### Robust Extensions:
# Add your own runtime and build-time extensions!
#
#### Next Steps:
# * [Visit the website]
# * [Read the wiki]
# * [Email the users group]
# * [Submit bug reports]
