This repository uses separate HTML and external CSS and JS files for clarity.

On the live site all of this is minified and inlined together into a single HTML file per tool. Application cache is used for offline access.


All code in this repository is dual licensed under the MIT/GPL licenses.

You dont have to do anything special to choose one license or the other and you dont have to notify anyone which license you are using. You are free to re-use parts of this code in commercial projects as long as the copyright header (as mentioned in GPL-LICENSE.txt and MIT-LICENSE.txt) is left intact.
