127:       end

Protected Instance methods

process_result()

Processes the options set by the command-line arguments. In particular, sets `@options[:for_engine][:filename]` to the input filename and requires the appropriate file.

This is meant to be overridden by subclasses so they can run their respective programs.

201:         require File.dirname(__FILE__) + "/../#{@name.downcase}"
202:       end
set_opts(opts)

Tells optparse how to parse the arguments available for the `haml` and `sass` executables.

This is meant to be overridden by subclasses so they can add their own options.
