join(string, ...)
Returns a new string formed by joining the strings using File::SEPARATOR.
File.join("usr", "mail", "gumby") #=> "usr/mail/gumby"
real_path = File.join Settings.real_dir, "#{real_name}.#{aaa}.apk"
dump( obj [, anIO] , limit=-1 ) → anIO
Serializes obj and all descendant objects. If anIO is specified, the serialized data will be written to it, otherwise the data will be returned as a String. If limit is specified, the traversal of subobjects will be limited to that depth. If limit is negative, no checking of depth will be performed.

end
o = Klass.new("hello\n")
data = Marshal.dump(o)
obj = Marshal.load(data)
obj.say_hello #=> "hello\n"
