This is original vimperator instapaper.js adopted for pentadactyl with some changes

• rl command works with some sites and add mobile versions to instapaper instead of full version:
  • livejournal.com
  • habrahabr.ru
  • www.trud.ru
  • lenta.ru
  • roem.ru
  • www.guardian.co.uk
  • news.rambler.ru
  • www.opennet.ru
• rl command gets login and password from Firefox Password Manager instead of plain text passwords in .pentadactylrc

Installing

Put instapaper.js into ~/.pentadactyl/plugin/.

Setting up

Then you should save your login and password in standart Firefox password manager on www.insapaper.com
