I think this is a problem with the program options.  Once multitoken is 
defined, the program options tried to read everything after the option 
as part of the option.  For example:

--config file.txt bob fish

If another option is placed after the multitoken, program option doesn't 
interpret it as another option but part of the multitoken.  For example:

--config file.txt bob fish --send 23

Program options read the above line as all part of the --config option.  
Shouldn't multitoken read tokens until the next option is found?
