#!/usr/bin/env node
//
// # Description
//
// Summarize the current page in a new tab, by processing it with the standalone readability
// library used for Firefox Reader View.
//
// # Prerequisites
//
// - Setting NODE_PATH might be required to point qutebrowser to your global node libraries:
// export NODE_PATH=$NODE_PATH:$(npm root -g)
// - Mozilla's readability library (npm install -g @mozilla/readability)
// - jsdom (npm install -g jsdom)
// - qutejs (npm install -g qutejs)
//
// # Usage
//
// :spawn --userscript readability-js
//
// One may wish to define an easy to type command alias in qutebrowser's configuration file:
// c.aliases = {"readability" : "spawn --userscript readability-js", ...}
