Коммичу изменения, но сам не знаю зачем.
Нужно l3-cgi переписать вообще с нуля.
Он мерзкий.

И продумать нужно, как он вообще должен работать.
Понятно, приблизительно, как он должен показывать журнал,
когда до него уже дошли,
но вот если не дошли, то что делать не понятно.
Короче, продумать систему навигации.
