Небольшая справка по веткам

cnddist – контейнер, в котором хранятся все дистрибутивы всех библиотек и программных пакетов, которые использовались при построении различных версий Contenido. Если какой-то библиотеки в данном хранилище нет, инсталлятор сделает попытку "подтянуть" ее с веба (например, с CPAN). Если библиотека слишком старая, есть очень большая вероятность, что ее там уже нет. Поэтому мы храним весь хлам от всех сборок. Если какой-то дистрибутив вдруг отсутствует в cnddist - напишите нам, мы положим его туда.

koi8 – отмирающая ветка, чей код, выдача и все внутренние библиотеки заточены на кодировку KOI8-R. Вносятся только те дополнения, которые касаются внешнего вида и функционала админки, баги ядра, обязательные обновления портов и мелочи, которые легко скопипастить. В дальнейшем планируется полная остановка поддержки по данной ветке.

utf8 – актуальная ветка, заточенная под UTF-8.

Внутри каждой ветки: core – исходники ядра; install – скрипт установки инсталляции; plugins – плагины; samples – "готовые к употреблению" проекты, которые можно поставить, запустить и посмотреть, как они работают.
