The `sass-convert` executable.
@param args [Array<String>] The command-line arguments
# File lib/sass/exec.rb, line 470 def initialize(args) super require 'sass' @options[:for_tree] = {} @options[:for_engine] = {:cache => false, :read_cache => true} end
Processes the options set by the command-line arguments, and runs the CSS compiler appropriately.
