The templates are used to generate the actual workflows that run on GitHub Actions. They use Jinja2 as the template engine.

Let's try to keep the Jinja usage to the bare minimum because, as time passes, the complexity just piles up making it harder to read and interpret the templates.

By default Jinja uses {% ... %}, {{ ... }}, {# ... #}, etc to do it's magic. In order not to clash with the GitHub Actions syntax, and to also avoid having to add bunch of {% raw %} ... {% endraw %} blocks, we changed some things:

• Instead of {% and %} use <% and %>
• Instead of {{ and }} use <{ and }>

The rest of Jinja2 defaults apply.
