+\featurelabel{slot-operator-deps} An operator slot dependency consists of a colon followed by one of
+the following operators:
+
+\begin{description}
+\item[*] Indicates that any slot value is acceptable. In addition, for runtime dependencies,
+indicates that the package will not break if the matched package is uninstalled and replaced by
+a different matching package in a different slot.
+\item[=] Indicates that any slot value is acceptable. In addition, for runtime dependencies,
+indicates that the package will break unless a matching package with slot equal to the slot of
+the best installed version at the time the package was installed is available.
+\end{description}
+
+To implement the equals slot operator, the package manager will need to store the slot of the
+best installed version of the matching package. The package manager may do this by appending
+the appropriate slot after the equals sign when saving the package's dependencies. This syntax
+is only for package manager use and must not be used by ebuilds.
