	-convert a subset of markdown into html and gemini files
		-tables & images not supported
		-code highlighting should work for HTML, no solution for Gemini

	-inline links are referenced using reference numbers [1] and are 
	listed below each paragraph. A full list of all links/references
	are displayed at the bottom. This scheme will work for both HTML 
	and gemini
	
	example:
		Implementing RC5 in Lua presented some minor challenges. Lua 
		likes to start its data structures at index 1, whereas C starts 
		at an index of 0. Converting the pseudocode from the paper [1] 
		to start counting at 1 instead of 0 took a little time, however 
		once you get used to the Lua way [2] things become pretty easy 
		to understand.
