-или
 /opt/zapret/init.d/openwrt/custom
+/opt/zapret/init.d/macos/custom
+Он считается устаревшим. Актуальный вариант - помещать отдельные скрипты там же, но в директорию "custom.d".
+Она будет просканирована стандартным образом, т.е. в алфавитном порядке, и каждый скрипт будет применен.
+Рядом имеется "custom.d.examples". Это готовые скрипты, которые можно копировать в "custom.d".
+Особо стоит отметить "10-inherit-*". Они наследуют стандартные режимы nfqws/tpws/tpws-socks.
+Полезно, чтобы не писать код заново. Достаточно лишь скопировать соответствующий файл.
+Можно наследовать и более сложным образом.
+"10-inherit-tpws4http-nfqws4https" наследует для http tpws, а для https и quic - nfqws.
 
-Нужно свой код вписать в функции :
+Для linux пишется код в функции
 zapret_custom_daemons
 zapret_custom_firewall
 zapret_custom_firewall_nft
+zapret_custom_firewall_nft_flush
 
-В файле custom пишите ваш код, пользуясь хелперами из "functions" или "zapret".
-Смотрите как там сделано добавление iptables или запуск демонов.
+Для macos
+zapret_custom_daemons
+zapret_custom_firewall_v4
+zapret_custom_firewall_v6
+
+zapret_custom_daemons поднимает демоны nfqws/tpws в нужном вам количестве и с нужными вам параметрами.
+Для систем традиционного linux (sysv) и MacOS в первом параметре передается код операции : 1 = запуск, 0 = останов.
+Для openwrt логика останова отсутствует за ненадобностью.
+Схема запуска демонов в openwrt отличается - используется procd.
+
+zapret_custom_firewall поднимает и убирает правила iptables.
+В первом параметре передается код операции : 1 = запуск, 0 = останов.
+
+zapret_custom_firewall_nft поднимает правила nftables.
+Логика останова отсутствует за ненадобностью. Стандартные цепочки zapret удаляются автоматически.
+Однако, sets и правила из ваших собственных цепочек не удаляются.
+Их нужно подчистить в zapret_custom_firewall_nft_flush.
+Если set-ов и собственных цепочек у вас нет, функцию можно не определять или оставить пустой.
+
+Если вам не нужны iptables или nftables - можете не писать соответствующую функцию.
+
+В linux можно использовать локальные переменные FW_EXTRA_PRE и FW_EXTRA_POST.
+FW_EXTRA_PRE добавляет код к правилам ip/nf tables до кода, генерируемого функциями-хелперами.
+FW_EXTRA_POST добавляет код после.
+
+В linux функции-хелперы добавляют правило в начало цепочек, то есть перед уже имеющимися.
+Поэтому специализации должны идти после более общих вариантов.
+Поэтому наследования идут с префиксом 10, а остальные custom скрипты с префиксом 50.
+Допустим, у вас есть особые правила для IP подсети youtube. Порты те же самые.
+Включен и общий обход. Чтобы youtube пошел приоритетом, скрипт должен применяться после
+общего обхода.
+Для macos правило обратное. Там правила добавляются в конец. Поэтому inherit скрипты
+имеют префикс 90.
+
+В macos firewall-функции ничего сами никуда не заносят. Их задача - лишь выдать текст в stdout,
+содержащий правила для pf-якоря. Остальное сделает обертка.
+
+Особо обратите внимание на номер демона в функциях "run_daemon" и "do_daemon", номера портов tpws
+и очередей nfqueue.
+Они должны быть уникальными во всех скриптах. При накладке будет ошибка.
+Поэтому используйте функции динамического получения этих значений из пула.
+
+custom скрипты могут использовать переменные из config. Можно помещать в config свои переменные
+и задействовать их в скриптах.
+Можно использовать функции-хелперы. Они являются частью общего пространства функций shell.
+Полезные функции можно взять из примеров скриптов. Так же смотрите "common/*.sh".
 Используя хелпер функции, вы избавитесь от необходимости учитывать все возможные случаи
 типа наличия/отсутствия ipv6, является ли система роутером, имена интерфейсов, ...
 Хелперы это учитывают, вам нужно сосредоточиться лишь на фильтрах {ip,nf}tables и
 параметрах демонов.
 
-Код для openwrt и sysv немного отличается. В sysv нужно обрабатывать и запуск, и остановку демонов.
-Запуск это или остановка передается в параметре $1 (0 или 1).
-В openwrt за остановку отвечает procd.
-
-Для фаервола кастом пишется отдельно для iptables и nftables. Все очень похоже, но отличается
-написание фильтров и названия процедур хелперов. Если вам не нужны iptables или nftables -
-можете не писать соответствующую функцию.
-
-Готовый custom скрипт custom-tpws4http-nfqws4https позволяет применить дурение
-tpws к http и nfqws к https. При этом поддерживаются установки из config.
-Его можно использовать как стартовую точку для написания своих скриптов.
