Hacker News Duplicate Detector

Hacker News Duplicate Detector (HNDD) is a Google Chrome extension that automatically
detects duplicate Hacker News (HN) submissions.

It is available from the Google Chrome Web Store:
https://chrome.google.com/webstore/detail/hacker-news-duplicate-det/ocagpmnfhgbgmbaaimpehpbnnplkmpkd

To use HNDD, install the extension, and it will work automatically on relevant HN pages.

Development

A different manifest.json is used for Chrome and Firefox. For development, create a symbolic link
manifest.json that points to either manifest_chrome.json or manifest_firefox.json, depending
on the environment.

To generate zip archives, run zip.sh.
