+# IPX start helper for systemd and OpenRC.
+#
+# This script reads its configuration from environment variables, typically
+# provided through /etc/conf.d/ipx.
+#
+# Manual interface format:
+#   <device>:<frame>:<netnum>
+#
+# Static route format:
+#   <target_network>:<router_network>:<router_node>
+#
+# Behaviour:
+#   - The first successfully configured interface becomes the primary IPX
+#     interface.
+#   - Missing interfaces are skipped.
+#   - Optionally, interfaces with no active link can also be skipped.
+#   - Static routes are added after interface configuration.
