+=head1 SYNOPSIS

+  ; .replyrc
+  [ResultCache]
+  variable = r
+
+=head1 DESCRIPTION
+
+This plugin caches the results of successful evaluations, and provides them in
+a lexical array (by default C<@res>, although this can be changed via the
+C<variable> option). This means that you can, for instance, access the value
+returned by the previous line with C<$res[-1]>. It also modifies the output to
+include an indication of where the value is stored, for later reference.
