Question about optparse/OptionParser callback.

[Steven W. Orr]

I'm new to python and I have a need to do this.

The Cookbook almost takes me there with:

def check_order(option, opt_str, value, parser):
     if parser.values.b:
         raise OptionValueError("can't use %s after -b" % opt_str)
     setattr(parser.values, option.dest, 1)

but warns that the "it needs a bit of work: the error message and the flag 
that it sets must be generalized". I do need to do my option processing in 
an option processor with many options. Is it possible to have a callback 
that knows how to access all of the options?

Many thanks. All I need is to be taught how to fish...
