Ah, terrific.  -m allows this feature, although i wonder why -m then  
makes regular "import", for those scripts that just want the default  
version, not useable (but i have not yet searched for this answer, so  
feel free to ignore).

Too bad a high-profile article on IBM got the details on this  
inaccurately.
