The list of languages supported with org-babel is now presented as an
org table.

Common variable values in org projects are now shared through one
variable each instead of having the value repeated.

only a couple of languages are supported directly by Org-mode itself, and
they need to be activated. Here are the languages I activated in my Org-mode

This is my configuration for exporting my dotfiles to my website in a web
format only. No PDFs or anything, just HTML. Please note that I do not use
that often anymore, I much prefer the automatic script that I have which
deploys through my Drone instance my website on git pushes.
And before we get into the actual configuration, I would like to introduce
a couple of variables. This is a bit more verbose than if I declared
everything manually, but now I can change all three values at the same
time without a hasle.

Now, here is my configuration. In this snippet, my org files located in my
source directory get exported in the HTML format and published to my
target directory on my remote server through SSH via TRAMP. A sitemap is
automatically generated, which comes in handy with the online sitemap that
is available through the navigation bar.
