From PMS:

12.1.2  REPLACING_VERSIONS and REPLACED_BY_VERSION

In EAPIs listed in table 12.2 as supporting it, the REPLACING_VERSIONS variable shall be defined in pkg_preinst and pkg_postinst. In addition, it may be defined in pkg_pretend and pkg_setup, although ebuild authors should take care to handle binary package creation and installation correctly when using it in these phases.

REPLACING_VERSIONS is a list, not a single optional value, to handle pathological cases such as installing foo-2:2 to replace foo-2:1 and foo-3:2.

In EAPIs listed in table 12.2 as supporting it, the REPLACED_BY variable shall be defined in pkg_prerm and pkg_postrm. It shall contain at most one value.
