Simplified restructure-text processing
This mini-framework aims to simplify the use of the restructure-text processing library, such that target document formats can easily be created with minimal lines of code.
The main idea is that you create a template (e.g. template.tex), then fill in the blanks with snippets compiled from restructure-text.
Currently supports some simple latex processing, which I use to generate academic papers and beamer lecture slides
