Hi
I found this script from http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/189858
it uses getopt module for managing cmd arguments, but I need it to work on mobile phones. I want to make a Mobile app using this script but I cant figure out how to change the comand Args to simple raw_inputs. can somebody please help me in this(i.e. removing parseArgs() and argsCallBack()?
I know that its not a polite request, but I really appreciate any help.
thanks in advance
