+User sets may be created by placing files in the \fB/etc/portage/sets/\fR

is generally used in conjunction with \fB\-\-update\fR. When used as
arguments to \fBemerge\fR sets have to be prefixed with \fB@\fR to be
recognized. Use the \fB\-\-list\-sets\fR action to display a list of

Resumes the most recent merge list that has been aborted due to an error.

.BR "\-\-buildpkgonly " (\fB\-B\fR)
Creates binary packages for all ebuilds processed without actually
merging the packages. This comes with the caveat that all build-time
dependencies must already be emerged on the system.
.TP
.BR "\-\-changed\-use"
-This is an alias for \fB\-\-reinstall=changed\-use\fR.
+Tells emerge to include installed packages where USE flags have
+changed since installation. This option also implies the
+\fB\-\-selective\fR option. Unlike \fB\-\-newuse\fR, the
+\fB\-\-changed\-use\fR option does not trigger reinstallation when

+.BR "\-\-dynamic\-deps < y | n >"
+In dependency calculations, substitute the dependencies of installed
+packages with the dependencies of corresponding unbuilt ebuilds from
+source repositories. This causes the effective dependencies of
+installed packages to vary dynamically when source ebuild dependencies
+are modified. This option is enabled by default.

+\fBWARNING:\fR
+If you want to disable \-\-dynamic\-deps, then it may be necessary to
+first run \fBfixpackages\fR(1) in order to get the best results. The
+\fBfixpackages\fR(1) command performs two different operations that can

.BR "-j [JOBS], \-\-jobs[=JOBS]"
Specifies the number of packages to build simultaneously. If this option is
given without an argument, emerge will not limit the number of jobs that can
run simultaneously. Also see the related \fB\-\-load\-average\fR option.
+Similarly to the \-\-quiet\-build option, the \-\-jobs option causes all
+build output to be redirected to logs.
Note that interactive packages currently force a setting
of \fI\-\-jobs=1\fR. This issue can be temporarily avoided
by specifying \fI\-\-accept\-properties=\-interactive\fR.
USE flags may be toggled by your profile as well as your USE and package.use
settings. If you would like to skip rebuilds for which disabled flags have
