# The +uv+ method applies syntax highlighting to source code embedded
# in a webpage. The UltraViolet highlighting engine is used for the HTML
# markup of the source code. The page sections to be highlighted are given
# as blocks of text to the +uv+ method.
#
# Options can be passed to the UltraViolet engine via attributes in the
# +uv+ method.
#
# <% uv( :lang => "ruby", :line_numbers => true ) do -%>
# # Initializer for the class.
# def initialize( string )
# @str = string
# end
# <% end -%>
#
# The supported UltraViolet options are the following:
#
# :lang : the language to highlight (ruby, c, html, ...)
# [defaults to 'ruby']
# :line_numbers : true or false [defaults to false]
# :theme : see list of available themes in ultraviolet
# [defaults to 'mac_classic']
#
# The defaults can be overridden for an entire site by changing the SITE.uv
# options hash in the Rakefile.
