A \fIset\fR is a convenient shorthand for a large group of
packages. Three sets are currently always available: \fBselected\fR,
\fBsystem\fR and \fBworld\fR. \fBselected\fR contains the user-selected
-"world" packages that are listed in \fB/var/lib/portage/world\fR,
-and nested sets that may be listed
-in \fB/var/lib/portage/world_sets\fR. \fBsystem\fR refers to a set of
+"world" packages that are listed in \fB/var/lib/portage/world\fR.
+\fBsystem\fR refers to a set of
packages deemed necessary for your system to run properly. \fBworld\fR
encompasses both the \fBselected\fR and \fBsystem\fR sets. [See
-\fBFILES\fR below for more information.] Other sets can exist depending
-on the current configuration. The default set configuration is located
-in the \fB/usr/share/portage/config/sets\fR directory. Note that a \fIset\fR
