Dual Web Setup

_info.md

Project Structure

app/local <- contains a full TYPO3 project (and a composer.json)
app/foreign <- contains a full TYPO3 project (and a composer.json)
packages/ <- contains multiple repositories
app/tests <- codeception acceptance tests which test the interaction between multiple repositories.

repos from packages are installed via composer in both "local" and "foreign" TYPO3 instances.
Both composer.jsons has a repositories section with type path and url /packages/*
