One file
The download carries every program at the version of its own release. It installs without the network.
Features
You choose
Each program shows what is installed: not yet, an older version to update, or already current.
The licences, first
Before anything is written, you read the licence of each program and of what it includes.
Installed as they install themselves
atelier runs each program's own --install: the same folder, menu entry and uninstaller as its own Install button.
For you alone
Everything goes in your profile. No administrator, no service, nothing in the system's folders.
From a script too
atelier list says what it carries; atelier install all installs without a window.
