HAML

HAML stands for HTML Abstraction Markup Language.

HAML was created for Ruby developers with the intent of providing a faster way of writing HTML code in one go.

It's not only a very complex, yet simple to read markup language, but a compiler at the same time, taking the HAML syntax, the developer's entered content, and outputting it as HTML code.

HAML is basically a template engine that merges content, placeholders, and HTML tags in one single file / place.

For CSS, SASS/SCSS does the same thing as HAML does for HTML. SASS is bundled with all HAML installations by default.

What is new in this release:
