Details:

This bug was originally reported on Issue 13 of the 'maneage-paper' project
<https://gitlab.com/makhlaghi/maneage-paper/-/issues/13>.

To fix the problem, we should add a step to see if the running-shell is
interactive. 

When it isn't interactive, and the desired option is not given ('--build-dir'
in the example above), the script should stop and warn the user by saying
something like this for the example above: "because you are running in
non-interactive mode, you need to use '--build-dir' to specify the build
directory". 

Of course, to be more clear, this check and its corresponding warning should
be done after printing the description of each step (so the user sees the
purpose of the problematic option just above it).
