Yes, that would be great. It might become a pain that we have at least 3 
different generations of those functions.

I think we should be very quick with a new release of odepkg, possibly even 
without Chiara's material. John ships already creates the windows binary with a 
patched version of odepkg...

I fully support this. Thanks! Let me know, if you need specific help with 
something.

One comment: we should also discuss what to do with dassl and daspk and when. I 
think we agreed to move them to odepkg eventually (and possibly change 
dassl_options and daspk_options to odeset for better compatibility).
