The AboutCode Toolkit and ABOUT files provide a simple way to document the origin, license, usage and other important or interesting information about third-party software components that you use in your project.

You start by storing ABOUT files (a small YAML formatted text file with field/value pairs) side-by-side with each of the third-party software components you use. Each ABOUT file documents origin and license for one software. For more information on the ABOUT file format, visit http://www.dejacode.org There are many examples of ABOUT files (valid or invalid) in the testdata/ directory of the whole repository.

The current version of the AboutCode Toolkit can read these ABOUT files so that you can collect and validate the inventory of third-party components that you use.

In addition, this tool is able to generate attribution notices and identify redistributable source code used in your project to help you comply with open source licenses conditions.

This version of the AboutCode Toolkit follows the ABOUT specification version 3.0 at: https://github.com/nexB/aboutcode-toolkit/blob/develop/SPECIFICATION.rst
