HTML Redemption Language (HRL for short) is a
language that redeems HTML by adding some tags
that should have been in HTML from the beginning.
The tags include "if", "include", "macro", and
(most importantly) "python". HRL is a preprocessor
language: its purpose is to generate static Web
pages, but with power. It's written in Python, and
its power comes from being able run embedded
Python scripts.
