def curl url, options={}
  options = {:method => "GET", :output => '/dev/null', :params => []}.merge(options)
  progress_meter = Chimps.verbose? ? '' : '-s -S'
  command = "#{curl_program} #{progress_meter} -X #{options[:method]} -o #{options[:output]}"
  command += " #{curl_params(options[:params])}" unless options[:params].empty?
  command += " '#{url}'"
  Chimps.log.info(command)
  system(command)
end
