+++ b/TODO
+Загрузку конфига
+Проверить всё с кавычками
+Неверно передаёт кавычки:
+__separate_sudocmd()
+А другие?
+readlink -f — что делать и нужен ли
+Нужен realfullpath
+Использование | less теряет код возврата команды. Нужно сделать nobash решение, которое сохранит статус
+Команда
+docmdmore
+Дописывать .service для systemd, если не указано другое.
+Установка (для отсутствующих файлов пакетов) и удаление (в любом случае) должны производиться с укороченными именами (которые воспримет верхний уровень)
+Чтобы было легко выстраивать цепочки, нужно ввод не с консоли (если есть) воспринимать как параметры.
+То же для EPM
 2. Дописать таблицу на вики на основании реализованных команд.
 3. Доделать и проверить deplist|requires
