  coderay foo.rb -loc                    # print LOC count, based on file extension and format
  coderay foo.rb > foo.html              # HTML page output to file, based on extension
  coderay -ruby < foo.rb                 # colorized output to terminal, based on lang
  coderay -ruby -loc < foo.rb            # print LOC count, based on lang
  coderay -ruby -page foo.rb             # HTML page output to terminal, based on lang and format
  coderay -ruby -page foo.rb > foo.html  # HTML page output to file, based on lang and format
