* Python module now has an additional option for the package to be
installed for easier installation of other versions.
* The Python module also has a restriction of installing version 3 and
above.
* The JavaScript module has been moved into a more general module for
web-based tools (including PHP).
One of the bigger changes is to make the setup hardware-independent
which is nice for easier (re-)installations.
Finally about time it happens.
Another big thing is the update of the README, now with some
self-reminding pitch why choose NixOS (or something similar like GuixSD)
which could be nice for other people too, provided they've come across
my NixOS config.
I made the module docstrings a bit more consistent (though still
useless, to be honest).
I've also updated config for Visual Studio Code.
