Sure. I just wrote this down in a half-delirious frame of mind suffering from a 
head-cold. And naturally there are combinations that don't make any sense, 
like "there's no no crc, but do check it...."
But then this is programmer-stuff and I would hope they'd understand, if 
they'd got as far as to understand they'd need this function. (I also still believe 
in Santa Claus, and if you've got some land for sale in Florida, I'm your guy...)

True enough. And exactly why I'd rather try to avoid those problems. But as 
you say, anyone can muck it up any way they like anyways.
