Overview

A parser for a simple template syntax, used for example to generate changelogs.

As a quick primer on the template syntax, a basic template looks like this:

{% each users %}
Name: {{name}}
Age: {{age}}

{% if birthday %}
This user is celebrating their birthday today! Yay!
{% end %}
{% end %}
