+// which are used to add command line arguments to a utility for all of the
+// passes that have been registered into the system.
+//
+// The PassNameParser class adds ALL passes linked into the system (that are
+// creatable) as command line arguments to the tool (when instantiated with the
+// appropriate command line option template). The FilteredPassNameParser<>
+// template is used for the same purposes as PassNameParser, except that it only
+// includes passes that have a PassType that are compatible with the filter
+// (which is the template argument).
+//
+// Note that this is part of the legacy pass manager infrastructure and will be
+// (eventually) going away.
