+# @DESCRIPTION:
+# A stand-alone implementation of the ver_replacing function aimed
+# for EAPI 9.  Intended to be used for wider testing of the proposed
+# function and to allow ebuilds to switch to the new model early, with
+# minimal change needed for the actual EAPI 9.
+#
+# @CODE
+# if ver_replacing -lt 1.2; then
+#     elog "The frobnicate command was dropped in version 1.2"
