Difficulty Switching command line for cgminer or sgminer

[mac-coin]

I'm sure we're all familiar with the idea of profit switching pools, or switching it yourself

But I've been thinking that the most profitable coin isn't also the most profitable by the time you've sold it.

I would like to be able to set up my miner and pick say 4 coins/pools and then same

If coin A diff is less then 20 mine
If coin B diff is less then 1200 mine
If coin C diff is less then 2 mine
If coin D diff is less then 10 mine

If more then 1 coin is lower mine in following order A,B,C,D

If all coin are above mine in the following order A,B,C,D



Any good programmers out there bored and want to have a play?
