Generate HTML emails for Nagios service and host alerts

We've open sourced a script we have created to turn your boring, plain-text Nagios emails into fancy, HTML, emails (with color!). You can check out the project on GitHub and take a look at the screenshots below.

The code is written in Node.JS, and the HTML templates are written using EJS. Installation is as easy as

[sudo] npm install -g nagios-html-email

and modifying a single Nagios config file.
