New options: options dependencies feature?

[Lev Serebryakov]

Hello, Freebsd-ports.

  Is it possible to express options' dependencies in new options
framework?

  I need option, which could be set if and only if some other option
is already selected.

  Now such situations are resolved via IGNORE which is set
 conditionally, but it is old-style, maybe now here is better method?
