semi-newbie ports question

[paul van den bergen]

just curious about how -release, -stable and -current operate wrt ports. More 
just a desire to confirm my understanding is correct...

I suppose that there are 2 port trees, -stable and -current?, so the shifting 
target that is ports is relevent to whichever branch you have.

alternately, there is just "ports" and the branch you have is a compile time 
variable...

how far can one be from the most recent -stable and still expect ports to 
work?
