  ## Filters ##
  ## these are meant to provide simple "transations"  for code ##
  ## Treat as shortcuts ##
  ## {{ expression | call | call | call }}

  ## Tags ##
  ## These are meant to be programmatic - if loops etc ##
  ## Treat as small widget / app ##
  ## {% title new title %}
  ## {% icon database %}
  %w(meta title csrf robots favicon js viewport stylesheet).each do |meta|
    Liquid::Template.register_tag meta, Tags::MetaTag

  Liquid::Template.register_tag 'icon',           Tags::IconTag

  ## Drops ##
  ## Provide access to backend data (User / Node / etc) ##
  ## Treat as object -- user.name etc ##
  ## {{ user.name }} {{ options.analytics }}
