patch.

 .TP
+.BR "\-\-rdeps\-only"
+Discard all build\-time dependencies. This option is commonly used together
+with \fBROOT\fR and it should not be enabled under normal circumstances. For
+currently supported \fBEAPI\fR values, the dependencies specified in the
+\fBDEPEND\fR variable are discarded. However, behavior may change for new
+\fBEAPI\fRs when related extensions are added in the future.
+.TP
 .BR "\-\-reinstall changed\-use"
 Tells emerge to include installed packages where USE flags have
 changed since installation.  Unlike \fB\-\-newuse\fR, this option does
 not trigger reinstallation when flags that the user has not
 enabled are added or removed.

+Install build\-time dependencies to \fBROOT\fR instead of /. This option

 This option is only valid when used with \fB\-\-resume\fR.  It removes the 
 first package in the resume list. Dependencies are recalculated for
