+# This PortGroup implements the "conflicts_build" option, which lets ports
+# specify that they would fail to build properly if certain other ports are
+# installed at configuration or build time. This is in contrast to the
+# MacPorts built-in "conflicts" option, which is for indicating activation-
+# time conflicts (i.e. ports that install files in the same locations).
+#
+# Ideally the conflicts_build option should be integrated into MacPorts base
+# instead of being a PortGroup.

+
+# conflicts_build: the list of ports with which this port conflicts at
+# configuration or build time.
