* About #+TITLE: Wolfe's Literate Emacs Config #+AUTHOR: Josh Wolfe #+HTML_HEAD: #+HTML_HEAD: #+HTML_HEAD: #+HTML_HEAD: #+HTML_HEAD: #+HTML_HEAD: #+LATEX_HEADER: \usepackage[margin=0.7in]{geometry} #+HTML: Build Status

This literate config is best read][here or in emacs. This page is generated and kept up to date using a combination of][travis ci and][ReadTheOrg. If you want to see the script that travis uses][here is the bash script it runs and][this is the =.el= file that it runs through emacs to generate the html page (this was mostly stolen from IvanMalison). Included in this section is also my export headers. These are responsible for including the ReadTheOrg theme as well as some metadata and options like title, author, table of contents etc. If you wish to see the headers I'm using,][this is the raw org file. * Variables Variables come at the beginning so that they're consistently available.
