Re,

I agree.
Actually, I had written a long time ago an universal function, able  
to handle any combination of any length.
One argument only: something like the strings I used in the tutorial  
as an introduction to specific formats.
But you have to understand well how to specify the format and it  
makes things a bit more complicated for anyone :-)
And the stack I have released is a simple tutorial to get any user  
started...
So I did no include it ;-)
