I'm guessing you are referring to "emerge --newuse".  That just selects 
packages
where a use flag for an ebuild is different from the last time the 
package was built.
I'm more interested in discovering brand new use flags.  Say some 
package, foo,
creates a new use flag, bar, then I'd like to see something like:

  New Use Flags:
    bar (used in:  foo)

It also would be nice to see when particular package changes the set of 
available
use flags between versions.

  Changed USE flag sets in the following packages:
    foo-1.0.0 (a b c)
    foo-1.0.1 (a c d e)

Thank you,
Roy
