15 That's right. So --changed-use only reemerges the package if the change
16 only affects your system, whereas -N will rebuild it even if the changed
17 flag is of no interest to you, such as when a flag you were not using is
18 removed. It saves recompiling packages for no reason, which is presumably
19 the reason it was added, it is a newer option than -N.
