goal code process .xls files in directory , convert them .csv. has worked in past after updating ruby , roo showing error below. using ruby 1.9.3-p362 , roo 1.11.2. 

require 'rubygems' require 'csv' require 'iconv' require 'mysql2' require 'mysql' require 'roo'  begin     dir["#{@work_path}/*.xls"].each |file|           begin           file_path = "#{file}"           file_basename = file.basename(file, ".xls")           xls = excel.new(file_path)           xls.to_csv("#{@kenshoo_work_path}#{file_basename}.csv")           @log.info("converted file #{file}")           fileutils.remove(file)           @log.info("deleted file #{file}")         rescue exception => e           @log.warn("unable convert file: #{file_basename} csv because #{e.message}")         end     end end

for every file following error message:

unable convert file: #{file} csv because uninitialized constant excel

any appreciated. thanks.

roo has excel class within roo:: namespace. need replace instances of excel roo::excel

the older versions did not namespace classes under roo::, explain why code broke after update.
