Parsing typical Windows command lines with optparse?

Is it possible to use optparse to parse typical Windows command lines?
Typical behaviour is like this:

- options are case insensitive: /RegServer is the same as /regserver

- use of '-' or '/' character for an option: -regserver is the same as
  /regserver

I have used my own hacked version of getopt for this behaviour, but I'm
missing the flexibility of optparse.
