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`.
