This document explains how to easily switch Lino versions individually on a server which hosts several Lino sites.
This document is not finshed, and there is no warranty.
For each Lino version “offered” on your server you create a new

In the project directory of every Lino site you create a symbolic link
env which points to the root directory of the virtualenv
to be used by that site.
You can then easily switch between environments because Lino, Django
and Apache activates them using the symbolic link
env in their
