+"\h{DESCRIPTION}
+
+The \cb{drop} command drops one or more packages from the configuration.
+If the packages being dropped still have dependents, then those will have
+to be drop as well and you will be prompted for a confirmation. Similarly,
+if the packages being dropped have prerequisites that are no longer needed,
+you will be offered to drop those as well.
+
+The \cb{drop} command also supports several \cb{--*-only} options that allow
+you to limit the amount of work that will be done.
