Comment (by kencu):

 Years ago, when I first came to MacPorts, I asked if all that supported-
 os-versions functionality could be encompassed in one single command that
 would accomplish all that, something like:

 {{{
 platform darwin
 supported_versions {}
 }}}
 where supported_versions would accept some bit of tcl like [>10], or
 [8-11], or etc.

 At the time, I was told this was impossible -- but I'd just like to open
 the idea again, as it would be much simpler in the end, I think.

 The default would just be as we are now -- all versions -- so it could be
 optionally added.
