Title: GitHub
Author: Brett Terpstra
Description: Github README style. Includes theme for Pygmentized code blocks.
---------------------------------------------------------------

Modified by Olivier Spinnler (OpSpl, dr-spinnler.ch):

	* nice colors imitating pen on paper
	* font family
	* maximum column width of 50 rem
	* column centered and not into window borders
	* table caption
	* figure caption
	* built-in paper background + ornament for separating lines (<hr> element)
	* special care of the vertical spacing
	* links and footnote markers are visible but discreet; they are hightlighted when hovered
	* vertical text positionning inside table cells and headers
	* easy to configure via variables at the top of the file

	Version date: 2020-10-10
