INTRODUCTION
============
WordGrinder is a simple, Unicode-aware word processor that runs on the
console. It's designed to get the hell out of your way and let you write;
it does very little, but what it does it does well.
It supports basic paragraph styles, basic character styles, basic screen
markup, a menu interface that means you don't have to remember complex
key sequences, HTML import and export, and some other useful features.
WordGrinder does not require X. It runs in a terminal."
It is supposed to be simple to install on Debian/Ubuntu systems.
