Eagle Data is part of the EagleLibs collection.
Simply add data.c and data.h to your project and go.
You may compile to static libraries if you wish.
Note: Dynamic library building is not yet supported.
The documentation is written in MediaWiki format and is located in the doc folder. There is a batch script for Windows users that will use Pandoc to render a markdown version of the readme (for GitHub) and render the main documentation as HTML.
Please see the main documentation for the API reference.
