 Replying to [comment:3 dluke@…]:
 > 2 reasons?

 At least that's what came into my mind so far, yeah. :)


 > it's easy to grep the output of 'port installed' to see which ports use
 some specific variant or grep (or specify) the output for a specific port.

 Yes, but port installed takes "ages" to process (~2 seconds on my
 machine), whereas grep variants.conf is "instant". :)


 > This might be useful, but I've never wanted/needed it.

 Oh I did on several occasions, for instance when fiddling with universal
 because of different circumstances where I did need 32bit libs too (a
 mess...) or tried to enable GTK's aqua interface... and disable it again
 as it sucked.


 > Remember, that variants should be kept to a minimum anyway...

 That may be true, but while we have it, why not improve this feature's
 handling? :)
