.SYNOPSIS
Control various actions to be taken on the RQDAassist repository/package.

.DESCRIPTION
The RQDAassist package repository in more complicated that some regular CRAN-compatible packages.
For instance, the RQDA packages and its dependencies have to be regularly cleaned up for tests
to be carried out on both binary and source installation options. Also, at this point, the package
is only working with R versions lower than 4.2. So when developing, one has to always remember to
use that version, when it's not the one pointed to by PATH. This script makes it easy to carry out
