-# @ECLASS-VARIABLE: CONFLICT_LIST
-# @DESCRIPTION:
-# Atoms mentioned in CONFLICT_LIST need to either be unmerged or upgraded
-# prior to this package being installed, but we don't want to have an explicit
-# dependency on that package. So instead, we do the following:
-#   1. When we are installed, ensure that the old version is not installed.
-#   2. If old version is installed, ask emerge to consider upgrading it.
-#      This consideration is listed as PDEPEND so that we don't add an
-#      explicit dependency on the other package.
-for atom in $CONFLICT_LIST; do
-	DEPEND="$DEPEND !!<=$atom"
-	RDEPEND="$RDEPEND !!<=$atom"
-	PDEPEND="$PDEPEND || ( >$atom !!<=$atom )"
