README.md


		* User-defined variables
		-* Preview variable values in real time
		+* Recursive variable definitions
		+* Real-time document preview with variable substitution
		* Platform independent (Windows, Linux, MacOS)
		-* Auto-insert variable names by typing in values followed by `Control+Space`
		+* Auto-insert variable names pressing `Control+Space`

		Future Features
		---
		* Spell check
		+* Search and replace, with or without variables
		* XML and XSL processing
		-* Search and replace text with variables
		* R integration using [Rserve](https://rforge.net/Rserve/)
		+* Re-organize variable names
