+# RustyDHCP configuration file (dhcp.conf).
+#
+# All server settings live here. Lines are `key = value`; blank lines and
+# lines starting with '#' or ';' are ignored. Keys are case-insensitive.
+# A trailing " # comment" (whitespace + '#') is stripped from values.
+# Duplicate keys: the last occurrence wins. Unknown keys are ignored.

+# Start the server with an optional config path (default: ./dhcp.conf):

+# If the file is missing or unreadable, the server logs a warning and uses
